Also, there is nothing stopping you doing:

   window.SetText( std::string( "Hello World" ).c_str());

and:

   ATL::CString text;
   window.GetText( text );
   return std::string( static_cast< const char * >( text ));

If you want to use TCHAR's:

   typedef std::basic_string< TCHAR > _tstring;

so you could have:

   namespace boost { namespace gui
   {
#if defined(BOOST_WINDOWS) || defined(BOOST_HAS_TCHAR)
      typedef std::basic_string< TCHAR > string;
#else
      typedef std::string string;
#endif
   }}

Then you can use gui::string in a generic, cross-platform way. Granted, it 
is (slightly) more work, but there is no need to use the string types 
provided by a particular GUI framework.
