Why don the Far Eastern fonts work?
These are 16 bit fonts, with thouousands and thouousands of characters. And the characters are more complex, which means (usually) more bits per character, which means more memory and more processing time. This includes fonts such as kana, kanji, song ti, mincho and gothic. (If you look carefully at the fully qualified font name for gothic via xfontsel, you’ll see clues. It’s a daewoo font. The gothic name is misleading to western minds, but no doubt means something to its author[s].) Check one of these out in a program that shows a font as pages (such as xfd).. You can keep hitting next page to see a new page of characters, almost forever.
