Hi, there.

Nice to see these Chinese releted patches being filed. But I think rationality of modification need explaining in detail. I've checked the patches briefly, see my comments below.

As changes is applied to FcBoolDefaults, doesn't this modification affect other font's rendering?

Considering the Uni-Han problem, no CJK fonts can be acceptable in China mainland, Taiwan, Japan and Korea due to character shape diversity. Exclusive lang tag can be use to match most suitable CJK font. So this is a designed feature.

I don't know the usage, nothing to comment.

I think this is absolutely needed.
