Description of problem:
In Fedora 16, both "simplified-chinese-support" and
"traditional-chinese-support" package groups are installed by default. The
problem is, simplified Chinese web pages (e.g. www.sina.com.cn) as displayed in
Firefox or Chrome will be rendered very fuzzily if
"traditional-chinese-support" is installed. If we remove
"traditional-chinese-support", simplified Chinese will be rendered
significantly better. So something in "traditional-chinese-support" is
affecting simplified Chinese rendering.
How reproducible:
Run the Fedora 16 Live CD (which has both "simplified-chinese-support" and
"traditional-chinese-support" package groups installed by default), start
Firefox, navigate to www.sina.com.cn. You'll see simplified Chinese characters
on that web page is rendered very fuzzily. Removing the
"traditional-chinese-support" package group will solve the problem.

Ideally, we should be able to have both TC and SC fonts installed without
affecting things. Perhaps this can be fixed in the fontconfig configuration?

Yes. we could improve the configuration file in fonts packages and actually
there are roughly two problems here.
1. cjkuni-ukai-fonts doesn't have the language specific rule. this would be the
root cause on this issue. this should also affects all of releases, even
rawhide.
2. as I filed so many bugs about malformed configuration, it's not yet fixed in
f16 branch for cjkuni-uming-fonts (Bug#837523) and wqy-zenhei-fonts
(Bug#837524). this may potentially causes a trouble in some cases.
So reassigning to cjkuni-ukai-fonts to fix it so far. also ping on those two
bugs to update in f16 too.

Sorry, not reproducible.
Do you have some customization in ~/.fonts.conf.d or ~/.fonts.conf?

assigning back to fontconfig again.
