The problem is that I cannot reproduce it with my font and pango-view either
anymore. However, the bug’s still visible in both Thunar and Exaile.

Also something strange: the text "最新动漫游戏音乐排行榜" is rendered as "  动
戏 乐   " in Thunar. A notable fact about this is that also only those three
characters are hinted in this Icedove mail window (and in pango-view), the other
ones are not. So it must be something about from which fonts the missing
characters are gathered to display the text. Obviously two (or more) different
fonts. The one which’s characters are not displayed seems to cause the trouble.
A strace on pango-view tells me that the fonts "KochiGothic Regular" and "simhei
0" are invoked.

Is there some way to get to know which parts of a text where rendered by using
characters from which font?

You’ll have to search the web, that’s how I got it. I can also send it to you if
you want to do some testing.
