_wfopen apparently does not yield correct filenames with 16-bit wchar_t string
===

when I code exactly like this:

       setlocale(LC_ALL,"");
       wchar_t myString2[] = { 0x0061, 0x2660, 0x2663, 0x2665, 0x2666, 0x0000 };
       fd = _wfopen(myString2, L"w");
or 

       fd = _wfopen(myString2, L"w, ccs=UTF-16");

The result is not what I expect. Expected: a♠♣♥♦, but explorer shows up  a and then 4 small squares. However, When I enter file rename in explorer, and then copy the filename, it is inserted correctly into an editor.
When I put a filename which shows up such characters, or let's say chinese characters are copied & pasted in an editor, the editor shows up the small squares into the file name.
Experiments with -fexec-charset=xxxx even don't yield the desired result. Given the results of the copy & paste experiments, I guess that something very stupid is going on. It this is true, the solution should be stupidly simple...

System: Win XP, Mingw 20120426, Ansi-C - so STLport shouldn't be needed.
