That makes this problem even more mysterious. All of
- 69-language-selector-zh-cn.conf
- 69-language-selector-zh-hk.conf
- 69-language-selector-zh-tw.conf
have Droid Sans Fallback as the first sans-serif font.

I'm out of ideas. To make progress with respect to this bug report, somebody using the languages in question has to play around with the font configuration files to figure out what needs to be changed.
