You have to use PyUnicode_AsWideChar() to convert a Python
Unicode object to a wchar_t representation.
Please don't make any assumptions on what Py_UNICODE maps
to and always use the the Unicode API for this. It is designed
to provide a portable interface and will not do more conversion
work than necessary.
