Ok, i think we got something: CodePageEntry is NULL:

ConPrintf1: 59
(dll\win32\kernel32\misc\nls.c:813) CodePageEntry is NULL
ConPrintf: -1

The code snippet:

    CodePageEntry = IntGetCodePageEntry(CodePage);
    if (CodePageEntry == NULL)
    {
        SetLastError(ERROR_INVALID_PARAMETER);
        DPRINT1("CodePageEntry is NULL\n");
        return 0;
    }

So IntWideCharToMultiByteCP returns 0? Why is then LastError not checked? 

I`ll proceed then with IntGetCodePageEntry(); investigation as hto recommended,
unless you guys have any other ideas.
