I am still trying to understand what a language tag is. If for a font, it means the font is designed for one region, then we can say category #1 and 2 is for zh_CN (mainland China) and probably zh_SG (Singapore), #3 is for zh_TW (Taiwan), zh_HK (Hong Kong) and zh_MO (Macau). I am not sure about #4 and 5. A font in category 4 or 5 could be for any of the above, and even ja_JP or ko_KR? For TTF font, there is another place to check: if it is designed for one region, it tends to have localized name tables. Or if the information is hard to get/guess, just maintain a separator database somewhere. It is bad or even dangerous to make computer overly smart. > Unifying fonts together to present a document works well when the selection > of fonts match the selection of langauges; a document with english and > traditional chinese sections should typeset the english sections in a > western font and the chinese sections in an traditional chinese font. Unifying a western font and a chinese font together is definitely desirable. Actually, I have seen lots of people asking for this feature. While the current codepoint based font priority/fallback mechanism has that illusion but unfortunately when applied to two Chinese fonts with different coverage, it really looks bad. Even worse, when several CJK fonts are combined together, it looks ugly. I would rather see blank square. What I am trying to say is there should be a limit when using this mechanism to increase coverage. I always heard people say that they want to see English in this font, Chinese in that font, etc. But never some Chinese in this font, other Chinese in that font - unless they have explicitly specified for that and they want to have total control of it, as in heading font, paragraph font, etc. From: Owen Taylor <[EMAIL PROTECTED]> > The question being discussed here is not combining multiple fonts ... > Pango already does this; it's pretty much a requirement if you > want to be able display multilingual text.

What I am trying to say is that the current implementation goes to far to combine different Chinese fonts together or even different CJK fonts together. In my opinion, that is bad. They could be in different combined font, not in one combined font.
