std::string and unicode

[John Ralls]

Yes, it's correct that std::string doesn't support Unicode. Unicode  
requires more than one byte per character (except for ASCII characters  
in UTF8), so wxChar becomes either 16bit or 32bit (depending on the  
platform). You'll have to transcode everything that you need to pass  
between std::string and wxString, and you'll have to wrap all of your  
literals in wxT macro. See the topic overviews on Unicode support and  
Conversion between Unicode and multibyte strings.

There's an alternative, but it requires that you switch to the  
development branch. The Unicode support for 2.9/3.0 has been rewritten  
to use UTF8, which uses 8-bit wxChar and is therefore somewhat  
interoperable with std::string if you're careful about it.
