 UNICODE!
 
 
 UNICODE!
 

+    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
+    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 on
+    win9x with the stock python.exe and pythonw.exe executables.
+    Instead I've had to rebuild the Python loaders linked with this
+    MSLU library from Microsoft.  I'd like to find a way to build
+    wxWindows/wxPython such that this is not needed...
+
+    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
+    from the C++ function will return a Python unicode object, and
+    parameters to C++ functions/methods that expect a wxString can
+    accept either a Python string or unicode object.  If a string
+    object is passed then it will be decoded into unicode using the
+    converter pointed to by wxConvCurrent, which will use the default
+    system encoding.  If you need to use a string in some other
+    encoding then you should convert it to unicode using the Python
+    codecs first and then pass the unicode string to the wxPython
+    method.

+Bad news: The API for adding tools to toolbars has changed again.
+Good news: Toolbar tools can now have labels!
