im tyring to get this to work:

#define UNICODE
#define _UNICODE
#include <wchar.h>

int main()
{
    wprintf(L"Hello World!\n");
    wprintf(L"£?, ?, ?!\n");
    return 0;
}

using visual studio 2008 express (on windows xp, if it matters). when i run this from the command prompt (started as cmd /u which is supposed to enable unicode ?) i get this:

C:\dev\unicodevs\unicodevs\Debug>unicodevs.exe
Hello World!
-ú8
C:\dev\unicodevs\unicodevs\Debug>

which i suppose was to be expected given that the terminal does not have the font to render those. but what gets me is that even if i try this:

C:\dev\unicodevs\unicodevs\Debug>cmd /u /c "unicodevs.exe > output.txt"

the file produced (even though its UTF-8 encoded) looks like:

Hello World!
壓

the source file itself is defined as unicode (encoded in UTF-8 without BOM). the compiler output when building:

any ideas on what am i doing wrong ? similar questions on ST (like this one: http://stackoverflow.com/questions/787589/unicode-hello-world-for-c) seem to refer to *nix builds - as far as i understand setlocale() is not available for windows.

i also tried building this using code::blocks/mingw gcc, but got the same results.
