Hey all, I am having some problems writting to a file in unicode inside my c program. I am trying to write a unicode Japanese string to a file. When I go to check the file though it is empty. If I try a non-unicode string it works just fine. What am I doing wrong?

        setlocale(LC_CTYPE, "");
        FILE* f;
        f = _wfopen(COMMON_FILE_PATH,L"w");
        fwprintf(f,L"???");
        fclose(f);
