Uses shell32.GetCommandLineArgvW to get sys.argv as a list of UTF-8
    strings.

    Versions 2.5 and older of Python don't support Unicode in sys.argv on
    Windows, with the underlying Windows API instead replacing multi-byte
    characters with '?'.

    Returns None on failure.

    Example usage:

    >>> def main(argv=None):
    ...    if argv is None:
    ...        argv = win32_utf8_argv() or sys.argv
    ...
