wxWindows/wxPython can be compiled with unicode support enabled or
disabled. Previous to wxPython 2.3.3 non-unicode mode was always
used. Starting with 2.3.3 either mode is supported, but only if
- it is also available in wxWindow on the platform. Currently
+ it is also available in wxWindows on the platform. Currently
wxWindows only supports unicode on MS Windows platforms, but with
the recent release of GTK+ 2.0 it is only a matter of time until
it can be done on wxGTK (Linux and other unixes) as well.
Unicode works best on platforms in the NT branch of the Windows
family tree (NT, win2k, XP) but it is now also possible to use the
same unicode binaries on win95/98/ME platforms as well! This is
- done by using a special library and DLL in the application called
- MSLU, (Microsoft Layer for Unicode). It simply gets out of the
- way if the app is run on an NT box, or if run on a win9x box it
- loads a special DLL that provides the unicode versions of the
- windows API. So far I have not been able to get this to work
- perfectly on win9x. Most things work fine but wxTaskBarIcon for
- example will cause a crash if used with the unicode build on
- win95.

So how do you use it? It's very simple. When unicode is enabled,
then all functions and methods in wxPython that return a wxString
Added wxLocale and wxEncodingConverter.
+A little black magic... When the C++ object (for a window or
+whatever) is deleted there is no way to force the Python shadow object
+to also be destroyed and clean up all references to it. This leads to
+crashes if the shadow object tries to call a method with the old C++
+pointer. The black magic I've done is to replace the __class__ in the
+Python instance object with a class that raises an exception whenever
+a method call (or other attribute access) is attempted. This works
+for any class that is OOR aware.
