+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Development Commands
+
+### Building the JAR
+The project uses IntelliJ IDEA project files (`.iml`) for building. Build the main library:
+- Main library JAR: `lib/TerrarumSansBitmap.jar`
+- Font test application JAR: `FontDemoGDX.jar`
+
+### Testing Font Rendering
+Run the font test application:
+```bash
+java -jar FontDemoGDX.jar
+```
+The test application demonstrates font rendering with text from `demotext_unaligned.txt` and outputs to `demo.PNG`.

+#### Pixel Artists Wanted: for Arabic (all four forms) and other Indian scripts (all the ligatures). Must willing to follow the styles and have a knowledge in Unicode. Your name will be inscribed in the list of contributors.
+
+You can contribute to the font by fixing wrong glyphs, suggesting better ones, extending character set (letters for other writing systems or filling in the blanks on the existing ones), or code for other game frameworks (not limited to Java). Please leave pull request for that.
+
+Font Spritesheets are stored in ```assets/graphics/fonts``` directory. Image format must be TGA with Alpha — no PNG. If someone needs PNG, they can batch-convert the font using utils like ImageMagick.
+
+
+#### Before getting started, you did read our design goals, right? Good. Now you may continue your awesome work.
+
+## Ascenders, descenders, width informations (aka Glyph Tags)
+
+![Alas, use more modern browser or get better internet connexion!](glyph_height_pos_annotation.png)
+
+Above image is a reference you can use while you draw some letters. Capital B is drawn as a reference. Orange-tinted area is for lowercase, x-height must be the same as that of said tinted area (lowercase Alpha is also drawn for the reference). NOTE THAT x-height is taller than centre bar (capital A is an exception). Height of the ascender of the lowercase letters must be the same as height of capital letters.
+
+Red-tinted area SHOULD NOT CONTAIN any dots, it's emptied for compatibility. (Slick2d—you can define size of "gaps" of the spritesheet, but you can't define horizontal and vertical gap separately)
+
+Blue-tinted area cotains width of the glyph in binary, uppermost dot is the Least Significant Bit.
+
+Green-tinted area contains extra informations, left blank for most cases. We'll call it Glyph Tags.
+
+Tinted-in-magenta shows the height where diacritics should be placed, for both uppercase and lowercase.
+
+Each cell is 16 px wide, and any glyph you draw **must be contained within leftside FIFTEEN pixels**.
+
+
+
+
+## Font Metrics for variable-width font sheets
+
+Although the font is basically a Spritesheet, some of the sheet expects variable widths to be supported. Any sheets with ```_variable``` means it expects variable widths. Anything else expects fixed width (regular Spritesheet behaviour). ```cjkpunct``` has width of 10, ```kana``` and ```hangul_johab``` has width of 12, ```wenquanyi``` has width of 16.
+
+### Parsing Glyph Tags
+
+![Sample of Font Spritesheet with annotation](width_bit_encoding_annotated.png)
+
+Width is encoded in binary bits, on pixels. On the font spritesheet, every glyph has vertical dots on their top-right side (to be exact, every (16k - 1)th pixel on x axis). Above image is a sample of the font, with width information coloured in magenta. From top to bottom, each dot represents 1, 2, 4 and 8. For example, in the above image, ! (exclamation mark) has width of 5, " (double quote) has width of 6, # (octothorp) has width of 8, $ (dollar sign) has width of 9.
+
+### Glyph Tags
+
+Rightmost vertical column (should be 20 px tall) contains the tags. Tags are defined as following:
+
+```
+(LSB) W -,
+      W  |
+      W  |= Width of the character
+      W  |
+      W -'
+      m --Is this character lowheight?
+      K -,
+      K  |= Tags used by the "Keming Machine"
+      K -'
+      Q ---Compiler Directive (see below)
+      n --,
+      Y -, `-Nudging Bits (see below)
+      X  |
+      Y  |= Diacritics Anchor Points (see below)
+      X -'  
+      A -,_ 0 Align  1 Align  0 Align   1 Align before
+      A -'  0 Left   0 Right  1 Centre  1 the glyph
+      D --Diacritics Type Bit (see below; not all diacritics are actually marked as a diacritics on the spritesheet)
+      S -,_ 0 Stack  1 Stack  0 Before  1 Up &
+(MSB) S -'  0 up     0 down   1 &After   1 Down* (e.g. U+0C48)
+
+Align Centre and Align Right will respect the diacritics anchor points.
+The Align Right AND Custom anchor point is being used for Thai diacritics.
+When a width AND diacritics type bit is set, the entire glyph is shifted to the right as specified and the space of same width will be inserted.
+(See SUNDANESE PAMINGKAL U+1BA1)
+
+Up&Down:
+1. when two pixels are both #00FF00 it's "don't stack"
+2. otherwise, it's actually up&down
+
+```
+
+#### Nudging Bits Encoding
+
+    <MSB,Red> SXXXXXXX SYYYYYYY 00000000 <LSB,Blue>
+
+Each X and Y numbers are Signed 8-Bit Integer.
+
+X-positive: nudges towards left  
+Y-positive: nudges towards up  
+
+#### Diacritics Anchor Point Encoding
+
+4 Pixels are further divided as follows:
+
+| LSB |   | Red | Green | Blue |
+| ------------ | ------------ | ------------ | ------------ | ------------ |
+| Y | Anchor point Y for: | undefined | undefined | undefined |
+| X | Anchor point X for: | undefined | undefined | undefined |
+| Y | Anchor point Y for: | (unused) | (unused) | (unused) |
+| X | Anchor point X for: | Type-0 | Type-1 | Type-2 |
+| **MSB** |   |   |   |   |
+
+    <MSB,Red> 1Y1Y1Y1Y 1Y2Y2Y2Y 1Y3Y3Y3Y <LSB,Blue>
+    <MSB,Red> 1X1X1X1X 1X2X2X2X 1X3X3X3X <LSB,Blue>
+
+where Red is first, Green is second, Blue is the third diacritics.
+MSB for each word must be set so that the pixel would appear brighter on the image editor.
+(the font program will only read low 7 bits for each RGB channel)
+
+#### Diacritics Type Bit Encoding
+
+    <MSB,Red> FFFFFFFF FFFFFFFF FFFFFFFF <LSB,Blue> (For Type-0)
+    <MSB,Red> TTTT0000 00000000 00000000 <LSB,Blue> (For Type-1 to Type-15)
+
+Certain types of diacritics have predefined meanings (but some writing systems define their own meaning e.g. Devanagari):
+
+* Type-0: Above
+* Type-1: Below (when it should be separated from being above)
+* Type-2: Overlaid (will shift down 2 pixels for lowheight glyphs instead of the default of 4 pixels)
+
+
+#### Compiler Directives
+
+    <MSB,Red> [Opcode] [arg1] [arg2] <LSB,Blue>
+
+Currently supported opcodes:
+
+*00000000: No-operation; does not use the Compiler Directive system.
+    
+*10000111: Replace a character with maximum 7 subchars.
+  Replacement characters are encoded vertically from X-zero, bit by bit
+  (colour of the pixel doesn't matter) with LSB sitting on Y-zero.
+
+*11111111: Tagging Used by the Subsystems. e.g. #FF0000 marks invalid combination.
+
+#### Stack Up/Down
+
+When the tag is stack-up, it'll be drawn 4 px lower if the underlying
+character is lowercase.
+
+#### Align-To-This-X-Pos
+
+Since this tag does not make sense for diacritics, they will use the value for compeletely different purpose:
+
+    0 : Nothing special
+    1 : Covers previous character; it's neither stack-up nor down.
+        Will be drawn 2 px lower if the underlying character is lowercase
+    2 : Joiner.
+    3..15: undefined
+
+#### Diacritics That Comes Before and After
+
+When this tag is set, the font compiler will replace this glyph with two extra code points given in the bitmap.
+
+To implement those, this two extra code points are needed, which are provided in the Unicode's Reference Chart (www.unicode.org/charts/PDF/Uxxxx.pdf) The code points must be "drawn" in the bitmap, in the same manor as a tagging system. The zeroth column (x = 0) has the "before" character, the first column (x = 1) has the "after". All nineteen pixels (bits) are read by the font, which encompasses U+0000..U+EFFFF
+
+For working examples, take a note at the bengali sprite sheet.
+
+This tag might be exploited as a general "replace this with these" directive, as long as you're replacing it into two letters. Such construction is FORBIDDEN due to diacritics incompatibility. Use Compiler Directives for such purposes.
+
+Also note that the font compiler will not "stack" these diacritics.
+
+#### The Keming Machine Tags
+
+Keming Machine Tags define the rough shape of the glyph. Please read `keming_machine.txt` for further information.
+
+
+#### NOTES
+- If glyphs are right or centre aligned, they must be aligned in the same way inside of the bitmap; the font compiler assumes every variable-width glyphs to have a width of 15, regardless of the tagged width.
+- If the diacritic is aligned before the glyph, the diacritic itself is always assumed as left-aligned, as the font compiler will exchange position of said diacritic and the glyph right before it.
+
+![Visual representation of left/right/centre align](alignment_illustration.jpg)
+
+(fun fact: it was drawn on Rhodia memopad with Lamy 2000, then photographed and edited on my iPhone. Letter used is a Cherokee WE Ꮺ)
+
+## Technical Limitations
+
+- Each spritesheet is 4096x4096 maximum, which is a size of 4K Texture. However it is recommended to be smaller or equal to 1024x1024.
+- Glyphs exceeding 15px of width needs to be broken down with 2 or more characters, or use EXTRAWIDE spritesheets.
+- Due to how the compiler is coded, actual glyph must have alpha value of 255, the tags must have alpha values LESS THAN 255 (and obviously greater than zero). RGB plane of the TGA image doesn't do anything, keep it as #FFFFFF white.
+
+## Implementation of the Korean writing system
+
+On this font, Hangul letters are printed by assemblying two or three letter pieces. There are 10 sets of Hangul letter pieces on the font. Top 6 are initials, middle 2 are medials, and bottom 2 are finals. On the rightmost side, there's eight assembled glyphs to help you with (assuming you have basic knowledge on the writing system). Top 6 tells you how to use 6 initials, and bottom 2 tells you how to use 2 finals.
+
+This is a Kotlin-like pseudocode for assembling the glyph:
+
+    // NOTE: this code implements modern Hangul only, in the unicode range of 0xAC00..0xD7A3.
+    // the spritesheet is made to accomodate Johab encoding scheme, but can still be used with the following code.
+    // for the code for full Johab encoding (U+1100.. that includes Old Korean), please refer to the actual code in the repo.

+# OTFbuild
+
+Python toolchain that builds an OpenType (CFF) and Web Open Font (WOFF2) font from the TGA sprite sheets used by the bitmap font engine.
+
+## Building
+
+```bash
+# builds both OTF and WOFF2
+make all
+```
+
+## Debugging with HarfBuzz
+
+Install `uharfbuzz` for shaping tests:
+
+```bash
+pip install uharfbuzz
+```
+
+Shape text and inspect glyph substitutions, advances, and positioning:
+
+```python
+import uharfbuzz as hb
+from fontTools.ttLib import TTFont
+
+with open('OTFbuild/TerrarumSansBitmap.otf', 'rb') as f:
+    font_data = f.read()
+
+blob = hb.Blob(font_data)
+face = hb.Face(blob)
+font = hb.Font(face)
+
+text = "ऐतिहासिक"
+buf = hb.Buffer()
+buf.add_str(text)
+buf.guess_segment_properties()
+hb.shape(font, buf)
+
+ttfont = TTFont('OTFbuild/TerrarumSansBitmap.otf')
+glyph_order = ttfont.getGlyphOrder()
+
+for info, pos in zip(buf.glyph_infos, buf.glyph_positions):
+    name = glyph_order[info.codepoint]
+    print(f"  {name} advance=({pos.x_advance},{pos.y_advance}) cluster={info.cluster}")
+```
+
+Key things to check:
+- **advance=(0,0)** on a visible character means the glyph is zero-width (likely missing outline or failed GSUB substitution)
+- **glyph name starts with `uF0`** means GSUB substituted to an internal PUA form (expected for Devanagari consonants, Hangul jamo variants, etc.)
+- **cluster** groups glyphs that originated from the same input character(s)
+
+### Inspecting GSUB tables
+
+```python
+from fontTools.ttLib import TTFont
+
+font = TTFont('OTFbuild/TerrarumSansBitmap.otf')
+gsub = font['GSUB']
+
+# List scripts and their features
+for sr in gsub.table.ScriptList.ScriptRecord:
+    tag = sr.ScriptTag
+    if sr.Script.DefaultLangSys:
+        for idx in sr.Script.DefaultLangSys.FeatureIndex:
+            fr = gsub.table.FeatureList.FeatureRecord[idx]
+            print(f"  {tag}/{fr.FeatureTag}: lookups={fr.Feature.LookupListIndex}")
+
+# Inspect a specific lookup's substitution mappings
+lookup = gsub.table.LookupList.Lookup[18]  # e.g. DevaConsonantMap
+for st in lookup.SubTable:
+    for src, dst in st.mapping.items():
+        print(f"  {src} -> {dst}")
+```
+
+### Checking glyph outlines and metrics
+
+```python
+font = TTFont('OTFbuild/TerrarumSansBitmap.otf')
+hmtx = font['hmtx']
+cff = font['CFF ']
+
+name = 'uni0915'  # Devanagari KA
+w, lsb = hmtx[name]
+cs = cff.cff.topDictIndex[0].CharStrings[name]
+cs.decompile()
+has_outlines = len(cs.program) > 2  # more than just width + endchar
+print(f"{name}: advance={w}, has_outlines={has_outlines}")
+```
+
+## Architecture
+
+### Build pipeline (`font_builder.py`)
+
+1. **Parse sheets** — `glyph_parser.py` reads each TGA sprite sheet, extracts per-glyph bitmaps and tag-column metadata (width, alignment, diacritics anchors, kerning data, directives)
+2. **Compose Hangul** — `hangul.py` assembles 11,172 precomposed Hangul syllables from jamo components and stores jamo variants in PUA for GSUB
+3. **Populate Devanagari** — consonants U+0915-0939 have width=0 in the sprite sheet (the Kotlin engine normalises them to PUA forms); the builder copies PUA glyph data back to the Unicode positions so they render without GSUB
+4. **Expand replacewith** — glyphs with the `replacewith` directive (opcode 0x80-0x87) are collected for GSUB multiple substitution (e.g. U+0910 -> U+090F U+0947)
+5. **Build glyph order and cmap** — PUA internal forms (0xF0000-0xF0FFF) get glyphs but no cmap entries
+6. **Trace bitmaps** — `bitmap_tracer.py` converts 1-bit bitmaps to CFF rectangle contours (50 units/pixel)
+7. **Set metrics** — hmtx, hhea, OS/2, head, name, post tables
+8. **OpenType features** — `opentype_features.py` generates feaLib code, compiled via `fontTools.feaLib`
+9. **Bitmap strike** — optional EBDT/EBLC at 20ppem via TTX import
+

+
+### OpenType features generated (`opentype_features.py`)
+
+- **ccmp** — replacewith expansions (DFLT); consonant-to-PUA mapping + vowel decompositions + anusvara upper (dev2/deva); vowel decompositions (tml2)
+- **kern** — pair positioning from `keming_machine.py`
+- **liga** — Latin ligatures (ff, fi, fl, ffi, ffl, st) and Armenian ligatures
+- **locl** — Bulgarian/Serbian Cyrillic alternates; Devanagari consonant-to-PUA mapping + vowel decompositions + anusvara upper (dev2/deva, duplicated from ccmp for DirectWrite compatibility)
+- **nukt, akhn, half, blwf, cjct, pres, blws, rphf, abvs, psts, calt** — Devanagari complex script shaping (all under both `script dev2` and `script deva`)
+- **pres** (tml2) — Tamil consonant+vowel ligatures

+- **ljmo, vjmo, tjmo** — Hangul jamo positional variants
+- **mark** — GPOS mark-to-base diacritics positioning
+- **mkmk** — GPOS mark-to-mark diacritics stacking (successive marks shift by H_DIACRITICS)
+
+### Devanagari PUA mapping
+
+The bitmap font engine normalises Devanagari consonants to internal PUA forms before rendering. The OTF builder mirrors this:
+
+| Unicode range | PUA range | Purpose |
+|---|---|---|
+| U+0915-0939 | 0xF0140-0xF0164 | Base consonants |
+| U+0915-0939 +48 | 0xF0170-0xF0194 | Nukta forms (consonant + U+093C) |
+| U+0915-0939 +240 | 0xF0230-0xF0254 | Half forms (consonant + virama) |
+| U+0915-0939 +480 | 0xF0320-0xF0404 | RA-appended forms (consonant + virama + RA) |
+| U+0915-0939 +720 | 0xF0410-0xF04F4 | RA-appended half forms (consonant + virama + RA + virama) |
+
+Mapping formula: `to_deva_internal(c)` = `c - 0x0915 + 0xF0140` for U+0915-0939.
+
+### Script tag gotcha
+
+When a script-specific feature exists in GSUB (e.g. `ccmp` under `dev2`), HarfBuzz uses **only** the script-specific lookups and does **not** fall back to the DFLT script's lookups for that feature. Any substitutions needed for a specific script must be registered under that script's tag.
+
+### languagesystem and language records
+
+The `languagesystem` declarations in the preamble control which script/language records are created in the font tables. Key rules:
+
+- `languagesystem` declarations must be at the **top level** of the feature file, not inside any `feature` block. Putting them inside `feature aalt { }` is invalid feaLib syntax and causes silent compilation failure.
+- When a language-specific record exists (e.g. `dev2/MAR` from `languagesystem dev2 MAR;`), features registered under `script dev2;` only populate `dev2/dflt` — they are **not** automatically copied to `dev2/MAR`. The language record inherits only from DFLT, resulting in incomplete feature sets.
+- Only declare language-specific records when you have `locl` or other language-differentiated features. Otherwise, use only `languagesystem <script> dflt;` to avoid partial feature inheritance that breaks DirectWrite and CoreText.
+
+### Inspecting feature registration per script
+
+To verify that features are correctly registered under each script:
+
+```python
+from fontTools.ttLib import TTFont
+
+font = TTFont('OTFbuild/TerrarumSansBitmap.otf')
+gsub = font['GSUB']
+
+for sr in gsub.table.ScriptList.ScriptRecord:
+    tag = sr.ScriptTag
+    if sr.Script.DefaultLangSys:
+        feats = []
+        for idx in sr.Script.DefaultLangSys.FeatureIndex:
+            fr = gsub.table.FeatureList.FeatureRecord[idx]
+            feats.append(fr.FeatureTag)
+        print(f"{tag}/dflt: {' '.join(sorted(set(feats)))}")
+    for lsr in (sr.Script.LangSysRecord or []):
+        feats = []
+        for idx in lsr.LangSys.FeatureIndex:
+            fr = gsub.table.FeatureList.FeatureRecord[idx]
+            feats.append(fr.FeatureTag)
+        print(f"{tag}/{lsr.LangSysTag}: {' '.join(sorted(set(feats)))}")
+```
+
+Expected output for dev2: `dev2/dflt: abvs akhn blwf blws calt ccmp cjct half liga locl nukt pres psts rphf`. If language-specific records (e.g. `dev2/MAR`) appear with only `ccmp liga`, the language records have incomplete feature inheritance — remove the corresponding `languagesystem` declaration.
+
+### Debugging feature compilation failures
+
+The build writes `debugout_features.fea` with the raw feature code before compilation. When compilation fails, inspect this file to find syntax errors. Common issues:
+
+- **`languagesystem` inside a feature block** — must be at the top level
+- **Named lookup defined inside a feature block** — applies unconditionally to all input. Define the lookup outside the feature block and reference it via contextual rules inside.
+- **Glyph not in font** — a substitution references a glyph name that doesn't exist in the font's glyph order (e.g. a control character was removed)
+
+### HarfBuzz Indic shaper (dev2) feature order
+
+Understanding feature application order is critical for Devanagari debugging:
+
+1. **Pre-reordering** (Unicode order): `ccmp`
+2. **Reordering**: HarfBuzz reorders pre-base matras (e.g. I-matra U+093F moves before the consonant)
+3. **Post-reordering**: `nukt` → `akhn` → `rphf` → `half` → `blwf` → `cjct` → `pres` → `abvs` → `blws` → `psts` → `haln` → `calt`
+4. **GPOS**: `kern` → `mark`/`abvm` → `mkmk`
+
+Implication: GSUB rules that need to match pre-base matras adjacent to post-base marks (e.g. anusvara substitution triggered by I-matra) must go in `ccmp`, not `psts`, because reordering separates them.
+
+### Cross-platform shaper differences (DirectWrite, CoreText, HarfBuzz)
+
+The three major shapers behave differently for Devanagari. The font registers all Devanagari features under **both** `dev2` (new Indic) and `deva` (old Indic) script tags. HarfBuzz and DirectWrite use `dev2`; CoreText uses `deva`.
+
+#### Script tag selection
+
+| Shaper | Script tag used | Indic model |
+|---|---|---|
+| HarfBuzz | `dev2` | New Indic (ot-indic2) |
+| DirectWrite | `dev2` | New Indic |
+| CoreText | `deva` | Old Indic |
+
+Both tags must exist, and all GSUB/GPOS features must be registered under both, otherwise CoreText silently breaks.
+
+#### Feature order differences
+
+**HarfBuzz (dev2, reference implementation)**:
+1. Pre-reordering: `locl` → `ccmp`
+2. Reordering (I-matra moves before consonant, reph moves to end)
+3. Post-reordering: `nukt` → `akhn` → `rphf` → `half` → `blwf` → `cjct` → `pres` → `abvs` → `blws` → `psts` → `haln` → `calt`
+4. GPOS: `kern` → `abvm` → `blwm`
+
+**DirectWrite (dev2)**:
+- `locl` → `nukt` → `akhn` → `rphf` → `rkrf` → `blwf` → `half` → `vatu` → `cjct` → `pres` → `abvs` → `blws` → `psts` → `haln` → `calt`
+- GPOS: `kern` → `dist` → `abvm` → `blwm`
+- **Does NOT apply `ccmp`** for the dev2 script. All lookups that must run before `nukt` (e.g. consonant-to-PUA mapping, anusvara upper) must be registered under `locl` instead.
+
+**CoreText (deva)**:
+- Applies `locl` and `ccmp`, but may apply `ccmp` **after** reordering (unlike HarfBuzz).
+- Post-reordering features same as above: `nukt` → `akhn` → `rphf` → ... → `abvs` → ... → `psts`
+- GPOS: `kern` → `abvm` (+ `mark`/`mkmk` if registered under `deva`)
+
+#### Key behavioural differences
+
+**1. ccmp timing (CoreText vs HarfBuzz)**
+
+HarfBuzz applies `ccmp` in Unicode order (before reordering). CoreText may apply it after reordering. This breaks adjacency-based rules:
+
+```
+# In ccmp — works on HarfBuzz (Unicode order: C + matra + anusvara):
+sub uni093F uni0902' lookup AnusvaraUpper;  # I-matra + anusvara
+
+# After reordering on CoreText: I-matra + [consonants] + anusvara
+# The I-matra and anusvara are no longer adjacent → rule fails
+```
+
+**Fix**: duplicate these rules in `abvs` (post-reordering) with wildcard gaps:
+```
+sub uni093F @devaAny uni0902' lookup AnusvaraUpper;
+sub uni093F @devaAny @devaAny uni0902' lookup AnusvaraUpper;
+```
+
+**2. Reph eligibility testing**
+
+| Shaper | Method |
+|---|---|
+| HarfBuzz | Pattern-based (RA + halant + consonant at syllable start) |
+| DirectWrite | `would_substitute([RA, virama], rphf)` with **Unicode** codepoints |
+| CoreText | `would_substitute()` with Unicode codepoints (same as DW) |
+
+The `rphf` feature must include a rule with the Unicode form of RA (`uni0930`), not just the PUA form. Otherwise DW and CT won't detect reph.
+
+**3. Within-lookup glyph visibility (CoreText)**
+
+In OpenType, a single lookup processes the glyph string left-to-right. Per spec, a substitution at position N should be visible when the lookup reaches position N+1. CoreText appears to **not** propagate substitutions within a single lookup pass to subsequent positions' backtrack context.
+
+Example: two rules in one anonymous lookup:
+```
+sub @trigger uF010C' lookup ComplexReph;     # rule at pos N: uF010C → uF010D
+sub uF010D uF016C' lookup AnusvaraLower;     # rule at pos N+1: needs uF010D in backtrack
+```
+
+On HarfBuzz/DirectWrite, rule 2 sees the updated `uF010D` at position N. On CoreText, it still sees the original `uF010C` → rule 2 fails to match.
+
+**Fix**: split into separate **named lookups** so each runs as an independent pass:
+```
+lookup AbvsPass1 {
+    sub @trigger uF010C' lookup ComplexReph;
+} AbvsPass1;
+lookup AbvsPass2 {
+    sub uF010D uF016C' lookup AnusvaraLower;
+} AbvsPass2;
+feature abvs {
+    script dev2; lookup AbvsPass1; lookup AbvsPass2;
+    script deva; lookup AbvsPass1; lookup AbvsPass2;
+} abvs;
+```
+
+**4. GPOS mark stacking heuristics**
+
+When two marks share the same base without MarkToMark, each shaper applies different internal Y adjustments:
+
+| Shaper | Internal Y shift |
+|---|---|
+| HarfBuzz | 0 (no heuristic) |
+| DirectWrite | -100 |
+| CoreText | -200 |
+
+No single GPOS Y value satisfies all three. **Fix**: use explicit MarkToMark positioning (e.g. `AnusvaraToComplexReph`) which suppresses shaper heuristics and gives consistent results across all three.
+
+**5. GPOS double-application with dev2+deva**
+
+When both script tags exist, CoreText/DirectWrite may merge lookup lists from both scripts. Inline (anonymous) GPOS rules create separate lookups per script → cumulative positioning doubles. **Fix**: use **named lookups** for all GPOS contextual positioning so both scripts reference the same lookup index.
+
+**6. mark/mkmk feature scoping**
+
+The `mark` and `mkmk` features are registered under `deva` (for CoreText) but **not** `dev2`. Under `dev2`, all mark positioning goes through `abvm` instead. This prevents double-application on HarfBuzz/DirectWrite where `abvm` already contains the same mark/mkmk lookups.
+
+```
+# GPOS features per script:
+# dev2/dflt: abvm kern
+# deva/dflt: abvm kern mark mkmk
+```
+
+#### Practical rules
+
+1. **Standalone lookups**: define all substitution/positioning lookups (e.g. `DevaConsonantMap`, `DevaVowelDecomp`, `ComplexReph`) **outside** any feature block, then reference from both `locl`/`ccmp` and script-specific features.
+2. **locl mirrors ccmp** for Devanagari: DirectWrite skips `ccmp`, so anything that must run early (consonant mapping, anusvara upper, vowel decomposition) must also be in `locl`.
+3. **abvs post-reordering fallbacks**: rules that depend on matra+anusvara adjacency (broken by reordering on CoreText) need wildcard-gap variants in `abvs`.
+4. **Separate lookup passes**: if rule B's backtrack context depends on rule A's output at an adjacent position, put them in separate named lookups. CoreText may not propagate within-pass substitutions.
+5. **Named GPOS lookups**: all contextual GPOS rules must use named lookups to avoid double-application across dev2/deva.
+6. **MarkToMark for multi-mark stacking**: never rely on shaper heuristics for positioning multiple marks on the same base — always provide explicit MarkToMark.

-This font is a bitmap font used in [my game project called Terrarum](https://gitlab.com/minjaesong/terrarum) (hence the name). The font supports more than 90 % of european languages, as well as Chinese, Japanese and Korean. More technical side, it supports Latin-1 Supplement, Latin Ext-A, Latin Ext-B, IPA Extension (required by some languages), Greek, Cyrillic (+ Bulgarian, Serbian variants) and the supplement, Armenian, Thai (beta version), Georgian, Unicode Punctuations, CJK Punctuations, Kana, Chinese (limited to Unihan and Ext-A), Hangul (all 11 172 possible syllables) and Fullwidth forms.

 The issue page is open. If you have some issues to submit, or have a question, please leave it on the page.
 
-#### Little notes
-- You can't display Bulgarian, Russian and Serbian variants at the same time without some more codes; ```reload()```ing them or creating multiple instances of the font would be the easiest solutions.
-- All Han characters are in Chinese variant, no other variants are to be supported as most Chinese, Japanese and Korean can understand other's variant and to be honest, we don't bother anyway.
+#### Notes and Limitations
+- Displaying Bulgarian/Serbian variants of Cyrillic requires special Control Characters. (`GameFontBase.charsetOverrideBulgarian` -- U+FFFC1; `GameFontBase.charsetOverrideSerbian` -- U+FFFC2)
+- All Han characters are in Mainland Chinese variant. There is no plan to support the other variants unless there is someone willing to do the drawing of the characters
+- Only the Devanagari and Tamil has full (as much as I can) ligature support for Indic scripts -- Bengali script does not have any ligature support
+- Slick2d versions are now unsupported. I couldn't extend myself to work on both versions, but I'm still welcome to merge your pull requests.
 
-## Contribution guidelines
+### Design Goals
 
-You can contribute to the font by fixing wrong glyphs, suggesting better ones, extending character set (letters for other writing systems or filling in the blanks on the existing ones), or code for other game frameworks (not limited to Java). Please leave pull request for that.
+- Sans-serif
+- Realise (some of) handwritten forms
+    - Combininig with the sans-serif, this stands for **no over-simplification**
+- Condensed capitals for efficient space usage
 
-Font Spritesheets are stored in ```assets/graphics/fonts``` directory. Image format must be TGA with Alpha — no PNG. If someone needs PNG, they can batch-convert the font using utils like ImageMagick.
+## Download
 
+- Go ahead to the [release tab](https://github.com/minjaesong/Terrarum-sans-bitmap/releases), and download the most recent version. It is **not** advised to use the .jar found within the repository, they're experimental builds I use during the development, and may contain bugs like leaking memory.

 ### How to Use Color Code
 
 Color codes are individual unicode characters. While you can somehow make a raw character and paste in on your code, it's certainly not desirable. Fortunately, we're also providing utility functions for the color codes.
 
-    GameFontBase.toColorCode(rgba4444: Int) -- returns String
+    GameFontBase.toColorCode(argb4444: Int) -- returns String
     GameFontBase.toColorCode(r: Int, g: Int, b: Int) -- returns String
     GameFontBase.toColorCode(r: Int, g: Int, b: Int, a: Int) -- returns String
 
-```rgba4444``` takes whole RGBA as input, that is, from 0x0000 to 0xFFFF. Most significant bits represents Red, and least significant bits represents Alpha (which should be fixed as F for the most time)
-```r, g, b(, a)``` takes RGB and A separately, in the range of 0..F. Any value exceeding the range **are unchecked and may wreak havoc**, so be careful.
+```argb4444``` takes whole ARGB (in that order) as input, that is, from 0x0000 to 0xFFFF.
+```r, g, b(, a)``` takes RGB and A separately, in the range of 0x0..0xF. Any value exceeding the range **are unchecked and may wreak havoc**, so be careful.
+
+U+100000 is used to disable previously-applied color codes (going back to original colour), even if it looks like ARGB of all zero.
 
 
-## Font metrics
+## Contribution guidelines
 
-Although the font is basically a Spritesheet, some of the sheet expects variable widths to be supported. Any sheets with ```_variable``` means it expects variable widths. Anything else expects fixed width (regular Spritesheet behaviour). ```cjkpunct``` has width of 10, ```kana``` and ```hangul_johab``` has width of 12, ```wenquanyi``` has width of 16.
-
-### Parsing glyph widths for variable font sheets
-
-![Sample of Font Spritesheet with annotation](https://github.com/minjaesong/Terrarum-sans-bitmap/blob/master/width_bit_encoding_annotated.png)
-
-Width is encoded in binary bits, on pixels. On the font spritesheet, every glyph has vertical dots on their top-right side (to be exact, every (16k - 1)th pixel on x axis). Above image is a sample of the font, with width information coloured in magenta. From top to bottom, each dot represents 1, 2, 4 and 8. For example, in the above image, ! (exclamation mark) has width of 5, " (double quote) has width of 6, # (octothorp) has width of 8, $ (dollar sign) has width of 9.
-
-### Implementing the Korean writing system
-
-On this font, Hangul letters are printed by assemblying two or three letter pieces. There are 10 sets of Hangul letter pieces on the font. Top 6 are initials, middle 2 are medials, and bottom 2 are finals. On the rightmost side, there's eight assembled glyphs to help you with (assuming you have basic knowledge on the writing system). Top 6 tells you how to use 6 initials, and bottom 2 tells you how to use 2 finals.
-
-This is a Kotlin-like pseudocode for assembling the glyph:
-
-    function getHanChosung(hanIndex: Int) = hanIndex / (21 * 28)
-    function getHanJungseong(hanIndex: Int) = hanIndex / 28 % 21

Although the shapes of typefaces are not copyrightable (the program codes—e.g. TTF—do), we would like to give a credit to the font and the people behind it.

-/**
- * LibGDX port of Terrarum Sans Bitmap implementation
- *
- * Filename and Extension for the spritesheet is hard-coded, which are:
- *
- *  - ascii_variable.tga
- *  - hangul_johab.tga
- *  - LatinExtA_variable.tga
- *  - LatinExtB_variable.tga
- *  - kana.tga
- *  - cjkpunct.tga
- *  - wenquanyi.tga.gz
- *  - cyrillic_variable.tga
- *  - fullwidth_forms.tga
- *  - unipunct_variable.tga
- *  - greek_variable.tga
- *  - thai_variable.tga
- *  - puae000-e0ff.tga
- *
- *
- * Glyphs are drawn lazily (calculated on-the-fly, rather than load up all), which is inevitable as we just can't load
- * up 40k+ characters on the machine, which will certainly make loading time painfully long.
- *
- * @param noShadow Self-explanatory
- * @param flipY If you have Y-down coord system implemented on your GDX (e.g. legacy codebase), set this to ```true``` so that the shadow won't be upside-down. For glyph getting upside-down, set ```TextureRegionPack.globalFlipY = true```.

+􏿆for free (as in freedom and without cost)􀀀
+
+There are many bitmap fonts on the internet. You care for the multilingual support, but alas!
+most of them do not support your language, vector fonts take too much time to load, and even
+then their legibility suffers because screw built-in antialias.
+
+You somehow found a multilingual one, and it makes your text as if they came straight from an old
+computer terminal, and you say:
+
+“Well, better than nothing… no, it’s ugly.”
+
+You speak Japanese and wish to support it, but then このクソなfont only good for displaying
+Japanese, it’s not even truly multilingual, and their English look uncanny and inconsistent.
+
+Eventually you just mix different fonts together, and the results were always mildly infuriating.
+
+No more suffering. This font has everything you need.

+􏿆The bitmap font for game developers who seek good font that has real multilingual support, for free (as in freedom and without cost)􀀀
+
+There are many bitmap fonts on the internet. You care for the multilingual support, but alas! most of them do not support your language, vector fonts take too much time to load, and even then their legibility suffers because screw built-in antialias.
+
+You somehow found a multilingual one, and it makes your text as if they came straight from an old computer terminal, and you say:
+
+“Well, better than nothing… no, it’s ugly.”
+
+You speak Japanese and wish to support it, but then このクソなfont only good for displaying Japanese, it’s not even truly multilingual, and their English look uncanny and inconsistent.
+
+Eventually you just mix different fonts together, and the results were always mildly infuriating.
+
+No more suffering. This font has everything you need.
