[Bug 207198] Re: Adobe Flash player 9 cannot display Chinese font
I am just a regular user, but I am not really sure if this is a solution. I guess the bug is that flashplayer queries for Bitstream and not for sans, which should provide the appropriate CJK font, depending on your fontconfig settings. But I could be wrong with this and the bug is actually somewhere else... Have you (or someone) contacted Adobe about this bug? Since all applications except Flash Player behave correctly, it would be pretty safe to assume that it is the culprit. I have looked for Japanese-related bugs in the Adobe bug database, and only found these two: https://bugs.adobe.com/jira/browse/FP-98 https://bugs.adobe.com/jira/browse/FP-136 The second is not relevant, and the first doesn't seem to be an exact hit, either. I guess opening a new one would not hurt, provided the problem is really with the plugin. So, IMHO all applications which handle text display, need to be fixed to support lang tags. Unfortunately this not something I can do. Yes, and let's not forget that it cannot even be done for all applications. Even if the Linux part is alright, what about, say, MSN in Kopete, etc? Yes, language tags are a good and long-missing feature, but until they become a reality, we still need to tell the system our preferences: Chinese or Japanese first. And for me, it's definitely Japanese. If it can be done in the 48-whatever.conf, fine, but it still seems like a big hack. -- Adobe Flash player 9 cannot display Chinese font https://bugs.launchpad.net/bugs/207198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 207198] Re: Adobe Flash player 9 cannot display Chinese font
On further investigation, it appears that this bug has to do with an interaction between: * /etc/fonts/conf.d/49-sansserif.conf (from fontconfig-config), and * /etc/fonts/conf.d/69-language-selector-zh-cn.conf (from language-selector-common) (substitute zh-cn for other locales) Quite a few Ubuntu users have blogged about this problem, and the usual quick fix is to get rid of /etc/fonts/conf.d/49-sansserif.conf , or change the append_last sans-serif therein to some other font. That said, I agree with Arne's assessment: Removing 49-sansserif.conf does not seem to be the right way, especially since this file is part of the upstream source, probably added by Keith Packard himself? This trick works for me: $ cd /etc/fonts/conf.d/ $ sudo mv 69-language-selector-zh-cn.conf 48-language-selector-zh-cn.conf Such that the Chinese-specific prepend config is sourced first. Please try and see if this trick works for you too. I also tried playing with the following command (under the zh_CN.UTF-8 locale): $ FC_DEBUG=1 firefox http://www.tudou.com/ Checking the of the debug output, it appears that Adobe Flash is trying to search for the appropriate font similar to the following command: $ FC_DEBUG=1 fc-match '/usr/share/fonts/truetype/ttf\-bitstream\-vera/Vera.ttf':scalable=true With 49-sansserif.conf and 69-language-selector-zh-cn.conf, fc-match returns: Vera.ttf: Bitstream Vera Sans Roman With 48-language-selector-zh-cn.conf and 49-sansserif.conf, fc-match returns: wqy-zenhei.ttf: WenQuanYi Zen Hei 中等 Arne, what do you think? Would that be an appropriate fix for language- selector?

[Bug 207198] Re: Adobe Flash player 9 cannot display Chinese font
Actually I don't know how the language selector works, but what about the language_selector/fontconfig files? Why aren't they used by the Flash Player? Also, if you make this change, will Latin (like English) text be displayed by the Chinese font? Because that just won't do, the Latin part of East Asian fonts is too ugly. And please don't forget about Japanese either :) (And here comes the question: which one should get a lower number? Japanese or Chinese? I would hate to see Chinese glyphs in Japanese text...) -- Adobe Flash player 9 cannot display Chinese font https://bugs.launchpad.net/bugs/207198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

According to Anthony's statement, flashplayer uses fc-match to query the Bitstream font. As the fontconfig files provided by language-selector *are* used by fontconfig, I guess the bug is that flashplayer queries for Bitstream and not for sans, which should provide the appropriate CJK font, depending on your fontconfig settings. But I could be wrong with this and the bug is actually somewhere else... I will investigate this issue further... please give me some time, as I'm flooded with work currently.

And please don't forget about Japanese either :) (And here comes the question: which one should get a lower number? Japanese or Chinese? I would hate to see Chinese glyphs in Japanese text...) This is an issue we cannot fix at the moment, but it's on my agenda. Proper handling of CJK fonts in applications would need the text which is to be rendered to be tagged with the appropriate language tag. Then, fontconfig can provide an appropriate font to render that text. In other words, the texts would need to use some markup language (like xml) to carry the language tag, and the applications, which display such texts, would need to parse those tags and ask the rendering engine to honor the lang tag. So, IMHO all applications which handle text display, need to be fixed to support lang tags. Unfortunately this not something I can do. This issue needs to be addressed upstream for each application and library separately. -- Adobe Flash player 9 cannot display Chinese font https://bugs.launchpad.net/bugs/207198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
