[PySide] non-ascii chars in python 2 on windows

[Joel B. Mohler]

The case correcting code in _utils.py has a bug on windows on python 
2.7.  The easy fix is included in the patch in the post-script.

qt-project grumblings:   I spent more time trying (and failing) to grok 
gerrit and gitorious than I did diagnosing and fixing this bug 
together.  Consider me vexed!  Also https://bugreports.qt-project.org 
doesn't acknowledge version 1.2.1 for PySide.
