[PyQt] including Unicode in QListWidget

[David Beck]

Hi, Phil

Thanks for your suggestion. I tried the workaround at the bottom, but it didn't seem to have any effect. However, my installation seems not to match the path you gave (I don't seem to have a /path/to/qt/ directory at all that I can find). I installed PyQt from PyQt-mac-gpl-snapshot-4.9.2-d49ae8bd9152.tar. It created a directory right next to itself called "PyQt" and the mkspecs folder is inside that. I went there, entered the ln command, ran python3.3 configure.py ..., make and make install, but I'm still having the same issue when I run the GUI.

If tonight's snapshot might be a fix, I'll try to install that—would that just be a matter of replacing the existing PyQt folder and going through the configure > make > make install routine? (Sorry for all the dumb questions—I'm willing to admit I'm way in over my head here.)
