 This could be a problem with my file patches as I have been using
PyUnicode_AS_UNICODE which will 4 byte strings if Py_UNICODE_WIDE is
defined. 4 byte strings can not be passed to the Windows API. So it looks
like PyUnicode_AsWideChar has to be used instead with a wrapper to allocate
enough memory to hold the resulting string.
