[PySide] trouble with special characters in widget.setToolTip()

It's not anything to do with the font.

Qt uses 16-bit unicode strings internally.  If you give a str to a PySide
function, it will need to decode it, and by default it will probably treat
it as ASCII.  If you want Qt to assume 8-bit strings are UTF-8 encoded, you
can use the following:

from PySide.QtCore import QTextCodec


However it would be better practice to pass it unicode strings if you can.
