[Bug 207198] Re: Adobe Flash player 9 cannot display Chinese font

[Anthony Fok]

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?

Thanks,

Anthony
