[Fonts]zh-hk font support/priority in Xft/Pango
Hello Keith and all, I was trying to run a Gtk2 application built with Xft/Fontconfig (2.0) and Pango under the zh_HK locale, on a system with only zh_CN (GB2312) and zh_TW (Big5) fonts installed. Under zh_CN and zh_TW locales, the correct fonts are chosen. Under zh_HK locale, however, since no zh_HK fonts were found on the system, the zh_CN font appears to have a higher priority over the zh_TW one, resulting in a funny-looking mosaic of text rendered with about 1/3 zh_CN and 2/3 zh_TW. This is my first problem. The second problem is that fontconfig 2.0 does not seem to recognize a zh_HK (HKSCS-2001) font as such. (This is on a different system where a full set of Chinese fonts is installed.) I have with me AR Mingti Light B5 v2.50 with HKSCS-2001, and here is roughly what fc-list tells me (from memory; I don't have access to that machine now): $ fc-list :lang=zh-cn FZShuSong\-Z01:style=Regular FZHei\-B01:style=Regular $ fc-list :lang=zh-tw AR Mingti Light B5:style=Regular AR PL Mingti2L Big5:style=Reguler [sic] AR PL KaitiM Big5:style=Regular $ fc-list :lang=zh-hk [no output] AR Mingti Light B5 should be complete, but just to make sure, I chdir to fontconfig/fc-lang, modified zh-hk.orth and kept only the first code (4E04?), ran 'xmkmf -a; make' etc., and fc-list :lang=zh-hk still showed no font. Now, I changed zh-hk.orth to just include zh-tw.orth, and finally fc-list :lang=zh-hk works, just as fc-list :lang=zh-mo does. So yes, there appears to be two related but separate issues: 1. When no zh_HK font is found, fontconfig (or is it Pango?) looks for zh_CN before zh_TW, but the right thing is to go to zh_TW first because zh_TW is 98% of the time adequate for zh_HK. (Yes, there are some 4800+ HKSCS characters, but their use is rare compared to the core Big-5 in a zh_TW font. 2. When a zh_HK font is available, fontconfig does actually recognize it. Could it have something to do with the algorithm where fontconfig decides a font to be either zh_CN or zh_TW (and not both?) And, hereby I admit my inadequacy, and I am no advanced programmer. I am not quite sure where to look. In fontconfig? Or in Pango? Any pointers would be helpful. Thanks in advance! :-) Cheers, Anthony -- Anthony Fok Tung-Ling ThizLinux Laboratory [EMAIL PROTECTED] http://www.thizlinux.com/ Debian Chinese Project [EMAIL PROTECTED] http://www.debian.org/intl/zh/ Come visit Our Lady of Victory Camp! http://www.olvc.ab.ca/ ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts

This is my first problem. We can solve this with a configuration change: match target=pattern test qual=any name=lang stringzh-hk/string /test edit name=lang mode=append stringzh-tw/string /edit /match This says that when asking for a font which supports 'zh-hk', accept as a reasonable substitute a font which supports 'zh-tw'. The second problem is that fontconfig 2.0 does not seem to recognize a zh_HK (HKSCS-2001) font as such. It's quite possible that the hk orthography is too selective; the HKSCS includes a lot of codepoints which may not be in the fonts you're interested in. You can check which codepoints are supported in that font using 'xfd'. If you can, send as many HKSCS fonts as you can along to me and I'll modify the orthography to fit them. The trick is to make sure that only fonts with reasonable HKSCS support are matched.

The trick is to make sure that only fonts with reasonable HKSCS support are matched. That's true. Yes, for starters, I suppose zh-hk.orth only need to cover HKSCS-1999 (with 116 less characters). Nevertheless, I reduced zh-hk.orth to only one single line (just the code 4E04) and fontconfig still wouldn't recognize any font as such, so I suspect the problem lies somewhere else. But yes, I shall do more experiment and let you know of the result. :-) Thanks again, Anthony -- Anthony Fok Tung-Ling ThizLinux Laboratory [EMAIL PROTECTED] http://www.thizlinux.com/ Debian Chinese Project [EMAIL PROTECTED] http://www.debian.org/intl/zh/ Come visit Our Lady of Victory Camp! http://www.olvc.ab.ca/ ___ Fonts mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/fonts
