[PyQt] trouble displaying unicode

[Maurizio Berti]

I just tried your example using decode(), and it works fine on Linux.
I got the infamous square when using with Wine, though; the same happens
when I just paste the correctly encoded text (copied from the linux-run
test), so I don't know if it's only a Wine issue, but you could try the
same and see if the unicode character shows up.
If that's the case, you should consider using encoded unicode strings by
default ( u'unicode string' ) or, maybe, using QString.fromUtf8 if you're
still using QString v1 api.
If the character doesn't show up instead, it might be a font issue (I don't
know much about font handling on windows, maybe you should specify a
different family?).
