Is utf8 just not supported by windows?

Answer 1

No, Windows doesn't support printing UTF-8 to the console.

When Windows says "Unicode", it means UTF-16. You need to use MultiByteToWideChar to convert from UTF-8 to UTF-16. Something like this:

char* text = "My UTF-8 text\n";
int len = MultiByteToWideChar(CP_UTF8, 0, text, -1, 0, 0);
wchar_t *unicode_text = new wchar_t[len];
MultiByteToWideChar(CP_UTF8, 0, text, -1, unicode_text, len);
wprintf(L"%s", unicode_text);

Answer 2

wprintf supposed to receive a UTF-16 encoded string. Use the following for conversion:

Use MultiByteToWideChar with CP_UTF8 codepage to do the conversion. (and don't do blind casting from char* into wchar_t* ).
