*It is* a mess. The wx rule is 'always use wxStrings unless you can't use it'. *Our* (IIRC consensus was reached) wish is: junk the whole wxString class since it's obsolete anyway (and convert the whole wx stuff to std::string). 'Fun' ensues since the std::string is not unicode under windows... well depending on the decided encoding.
Part of the problem is that a wxChar (so the wxString element) can be a char or a wchar_t (or something else, it seems) depending on the platform *and* wxWidget compile options! The fact that Linux/Macos X uses UTF-8 (so a MBCS encoding) while Windows is still stuck to 16-bit unicode (so not even UTF-16!) complicates life anyway... the gtk people uses UTF-8 under Windows too, ISO says to use wstring (which *nobody else* uses and suck 4 bytes a character), so anyway portable string handling is suffering XD
And, yes, you can build a 'differently compatible' wxWidget library when configuring it...
Another thing, good luck when you stumble on the hashtable declaring macros, too...
