[wxPython-users] ANN: GUI2Exe for wxPython :-D

[roee shlomo]

Hi Andrea and Kevin,

The workaround suggested by Andrea actually worked.
I have tried different kinds of encodings including
locale.getpreferredencoding() and sys.getfilesystemencoding() but only utf-8
worked.

The latest release from Andrea's site works perfectly as far as I can tell.
Cheers,
Roee.
