+#### Notes and Limitations
-- To display Bulgarian/Serbian variants, you need special Control Characters. (GameFontBase.charsetOverrideBulgarian -- U+FFFC1; GameFontBase.charsetOverrideSerbian -- U+FFFC2)
+- Displaying Bulgarian/Serbian variants of Cyrillic requires special Control Characters. (`GameFontBase.charsetOverrideBulgarian` -- U+FFFC1; `GameFontBase.charsetOverrideSerbian` -- U+FFFC2)
-- All Han characters are in Chinese variant, no other variants are to be supported as most Chinese, Japanese and Korean people can understand other's variant and as long as I can, we don't bother anyway.
+- 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
-- Indian script in general is not perfect: right now this font will never do the proper ligatures (I can't draw all the 1 224 possible combinations). Hopefully it's still be able to understand without them.
+- 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.

 ### 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.
