Ok, thank you for the explanation.

Well, let's assume I have an unicode build of wxPython. Then Roee
sends me his database of GUI2Exe projects, and he has put in there
project names with hebrew letters (or cyrillic or whatever). My
database pre-processing will not blink, but on my machines
wx.GetDefaultPyEncoding() returns either 'cp1251' (here at work) or
'ascii' at home. Will it harm if I receive Roee's database?

sys.getdefaultencoding() seems not enough to work with bsddb, also
Roee reported the same problem. And I found exactly the same when
assigning project names with accented letters (french, german and
similar). I saved a project in the database with this strange name,
closed GUI2Exe, reopened it and the project name was completely
screwed up :-(
