So what? that's not a bug in vlgothic-fonts though ;)

Not really. I have looked at language-selector though, basically what they have
done is same to what we do. only difference is, they've done to switch the
config physically outside fontconfig, but we do in fontconfig with checking the
language.

I don't think Ubuntu way is the right thing since it doesn't use the expected
fonts for the language. i.e. if select -zh-cn.conf, even Japanese text will be
rendered with Chinese font.

I'm not sure what you mean. the language-specific overrides rule is to do that.
but it really conflicts to the simple priority list. actually getting rid of it
makes the language-specific overrides rule working and this issue is also gone.
Since we've sometimes ever seen the font order issue between Chinese and
Japanese desktop/installer etc, I'm beginning to think that the simple priority
list is evil.

I don't like the language-selector idea, because it may be hard to get rid of
that feature once we've implemented. people may gets confused with it.
That would be good to update all of fonts in F-12 which has the simple priority
list and are supposed to work for the specific language.
