String To Lower/Upper in C++

Question

What is the best way people have found to do String to Lower case / Upper case in C++?

The issue is complicated by the fact that C++ isn\'t an English only programmi

Answer 1

I have found a way to convert the case of unicode (and multilingual) characters, but you need to know/find (somehow) the locale of the character:

#include 

_locale_t locale = _create_locale(LC_CTYPE, "Greek");
AfxMessageBox((CString)""+(TCHAR)_totupper_l(_T('α'), locale));
_free_locale(locale);

I haven't found a way to do that yet... I someone knows how, let me know.

Setting locale to NULL doesn't work...
