Yes, sorry, fn_str() would still be needed, but it wouldn't need to do 
anything usual (and anything at all in UTF8 build).

Again, this shouldn't be done in any MB<->WC converter, because it's 
an operation done on Unicode points, so it should be done on wxString 
(or wchar_t*) data rather then when converting from MB to WC. Of 
course, we'd still need some convenience function for wxMac's use or 
maybe wxConvFile should do it automagically on Mac in its MB->WC 
conversion? But I think it shouldn't be part of wxMBConvUTF8 (or any 
other general-purpose class).

Regards,
Vaclav
