  95 <h2><center>wxPython Unicode Support</center></h2>
  96
  97 wxWindows and wxPython can be compiled with unicode support enabled or
  98 disabled.  Previous to wxPython 2.3.3 non-unicode mode was always
  99 used.  Starting with 2.3.3 either mode is supported, but only if it is
 100 also available in wxWindow on the platform.  Currently wxWindows only
 101 supports unicode on MS Windows platforms, but with the recent release
 102 of GTK+ 2.0 it is only a matter of time until it can be done on wxGTK
 103 (Linux and other unixes) as well.
 104 <p>
 105 When unicode is enabled, then all functions and methods in wxPython
 106 that return a wxString from the C++ function will return a Python
 107 unicode object, and parameters to C++ functions/methods that expect a
 108 wxString can accept either a Python string or unicode object.  If a
 109 string object is passed then it will be decoded into unicode using the
 110 converter pointed to by wxConvCurrent, which will use the default
 111 system encoding.  If you need to use string in some other encoding
 112 then you should convert it to unicode using the Python codecs first
 113 and then pass the unicode to the wxPython method.
