 This font is a bitmap font used in my game project, Terrarum (hence the name). It Supports ExtA, Romanian (subset of ExtB), Cyrillic, Greek, Chinese, Japanese and Korean.

 ## Font metrics
 
 The font expects both variable widths and fixed width to be supported. Any images with ```_variable``` means it expects variable widths. Anything else expects fixed width. ```romana_narrow``` has width of 6 (no, not 5), ```romana_wide``` has width of 9, ```cjkpunct``` has width of 10, ```kana``` has width of 12, ```hangul_johab``` has width of 11, ```wenquanyi``` has width of 16.

 ### Implementing Korean writing system
 
-There are 10 sets of Hangul glyph pieces. Top 6 concerns initials, middle 2 concerns medials, and bottom 2 concerns 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.
