[PyQt] Unicode characters in QTreeView

[Doogster]

Japanese characters aren't displaying properly in my QTreeView.

What should I do?

Here's a screenshot (the bottom line should be in Japanese).

This is an MPD client and the rows are id3 tags. The line in question
does display properly in Amarok and (significantly, since it uses the
same python-mpd library I'm using) in Sonata. That means there's
nothing wrong with either the data or the library I'm using to read
it; the fault is with my GUI code.
