Oops, message got sent when I pressed some keys by accident.
So #1 == #3 and #2 uses wxConvUTF8 instead of wxConvCurrent.
I know that wxUSE_UNICODE uses wchar_t
wxConvCurrent == &wxConvLibcObj ==
#ifdef __WINDOWS__
static wxMBConv_win32 wxConvLibcObj;
#elif defined(__WXMAC__) && !defined(__MACH__)
static wxMBConv_mac wxConvLibcObj ;
#else
static wxMBConvLibc wxConvLibcObj;
#endif
I think we need to have answers to these questions.
How do you know if you're using UTF8?
How do you set wxWidgets to use or not use UTF8 if you want to?
If you get text from the clipboard, can it be in UTF8?
and finally, is wxConvCurrent supposed to handle UTF8 as is?
I personally don't have any idea and would naively think that
wxConvCurrent instead of wxConvUTF8 is the right thing to do.
