Does the new library also deal with the ongoing issues with Unicode
support? AIUI there's some fundamental problem with Tkinter which
means that (possibly only on Windows?) non-BMP characters simply can't
be displayed. To me, that's a pretty bad flaw - we should be aiming
new projects at complete Unicode support, which means Python 3 and a
good GUI toolkit.

PyGTK is a bit clunky in some areas, but I have GTK experience from
other languages, so that's the one I personally use.
