 #17550. It's possible that a Simplified Chinese edition of Windows may use
 the localized name as its primary font name. On the other hand, I couldn't
 find any evidence of a localized-name version of this font. So I'm hopeful
 this will be enough to work.

 Microsoft YaHei is 微软雅黑. In the same way, Microsoft YaHei UI should be
 微软雅黑 UI, but I can't find the Chinese name in my system.The
 differences between the two is that (at least) numberic characters and
 punctuation marks are rendered in different styles.It won't break whole TB
 UI like yawning mentioned.

 Some users say fonts in new version are ugly. If that's a reasonable
 request, I suggest 微软雅黑 Light and Microsoft YaHei UI Light should be
 whitelisted.
