I don't like that std::basic_string is hardcoded in the interface.
I talked briefly with Bill about it in Redmond. I would rather see
a more complicated coverter class and then an easy function interface on top
of that, maybe like

vector<char> bytes;
convert_to_bytes<utf8_enc>( L"foo", bytes );
vector<wchar_t> wides;
convert_to_wides<utf8_enc>( bytes, wides );

or something.
