Thanks for the additional info. Then we can leave that theory behind.
It was not quite correct when I said that WenQuanYi Zen Hei was the previous default font for Chinese. It was in 13.10 in case of a Chinese locale, but that does not apply to your situation.
The previous package for rendering Chinese, that was previously installed for all users, was fonts-wqy-microhei, and the new replacement is fonts-droid.

So let's try to verify that the issue is related to this change: Can you please
1) reinstall fonts-wqy-microhei and
2) uninstall fonts-droid
and let us know if the mixed font problem disappears that way.
