> Is CJK support any special compared to "Western" font rendering except that the font files are much bigger? I'm mostly thinking about the composing. For example, the character '한' is composed with 'ㅎ', 'ㅏ', 'ㄴ'. There are multiple unicode representations for each character, which means there's a one code point '한' representation and it's also allowed to have a 'ㅎ+ㅏ+ㄴ' representation. If the program is just naively searching through the code points the font is supporting, 'ㅎ+ㅏ+ㄴ' won't be rendered properly. (In the real world, most non-Korean companies that implement custom text rendering, even big ones like Adobe get this wrong.)
