Description of problem:
All of detailed information is available on my post at the fonts list:
http://lists.fedoraproject.org/pipermail/fonts/2010-March/001117.html

binding="same" in the fontconfig config file prevents to apply the rule for the
specific
language only properly. As a result, fonts is used for non-targetted languages
and it may gives different look and feel in some cases.

I'd propose to get rid of binding="same" from:
 65-wqy-zenhei.conf

I tested the changes on Fedora 13, and the result is as following:
(font config file is from http://pwu.fedorapeople.org/fonts-conf/).

1. Before removing binding="same" or binding="strong":
+ fc-match sans
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "中等"
+ fc-match sans:lang=zh
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=zh-cn
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=zh-tw
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=zh-hk
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=en
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=en-us
DejaVuSans.ttf: "DejaVu Sans" "Book"

2. After removing binding="same" or binding="strong":
+ fc-match sans
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "中等"
+ fc-match sans:lang=zh
uming.ttc: "AR PL UMing TW" "Light"
+ fc-match sans:lang=zh-cn
uming.ttc: "AR PL UMing TW" "Light"
+ fc-match sans:lang=zh-tw
uming.ttc: "AR PL UMing TW" "Light"
+ fc-match sans:lang=zh-hk
uming.ttc: "AR PL UMing TW" "Light"
+ fc-match sans:lang=en
DejaVuSans.ttf: "DejaVu Sans" "Book"
+ fc-match sans:lang=en-us
DejaVuSans.ttf: "DejaVu Sans" "Book"

It seems that removing the binding="same" helps split between English and
Chinese fonts.

Testing result:
# rpm -qa wqy-zenhei-fonts
wqy-zenhei-fonts-0.9.45-2.fc13.noarch
# fc-match monospace:lang=en
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# fc-match monospace:lang=en-us
DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"
# fc-match monospace:lang=zh
wqy-microhei.ttc: "WenQuanYi Micro Hei" "Regular"
# fc-match monospace:lang=zh-cn
wqy-zenhei.ttc: "文泉驛正黑" "Regular"
# fc-match monospace:lang=zh-hk
hanazono.ttf: "HanaMin" "Regular"
# fc-match monospace:lang=zh-sg
wqy-zenhei.ttc: "文泉驛正黑" "Regular"
# fc-match monospace:lang=zh-tw
hanazono.ttf: "HanaMin" "Regular"

Though the above result looks good, this isn't by 65-wqy-zenhei.conf. but by
the implicit rules in fontconfig that happens on when no appropriate fonts
matched by the rules. so

<test name="lang">
    <string>zh</string>
  </test>

should be:

<test name="lang">
    <string>zh-cn</string>
    <string>zh-sg</string>
  </test>

# fc-match sans:lang=en
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match sans:lang=en-us
DejaVuSans.ttf: "DejaVu Sans" "Book"
# fc-match sans:lang=zh
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match sans:lang=zh-cn
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match sans:lang=zh-hk
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match sans:lang=zh-sg
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match sans:lang=zh-tw
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"

I'd add same comment above for this one as well. also that would be good to
rename 65-wqy-zenhei.conf to 65-0- or something like that to apply this prior
to 65-nonlatin.conf.

# fc-match serif:lang=en
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=en-us
DejaVuSerif.ttf: "DejaVu Serif" "Book"
# fc-match serif:lang=zh
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match serif:lang=zh-cn
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match serif:lang=zh-hk
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match serif:lang=zh-sg
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"
# fc-match serif:lang=zh-tw
wqy-zenhei.ttc: "WenQuanYi Zen Hei" "Regular"

No explicit rules for serif in wqy-zenhei-fonts. this would be a kind of
side-effect of 65-nonlatin.conf.

# for i in $(ls /usr/share/locale|grep -v -E "^(zh)$"); do fc-match
sans:lang=$i|grep -E "^(WenQuanYi Zen Hei)$"; [ $? = 0 ] && echo $i; done
#

No affects to other languages.
