Note that the implementation will bomb in several places if
Py_UNICODE is a signed type.

Py_UNICODE was never intended to be a signed type, so the proper
fix would be to add logic so that Py_UNICODE gets forced to be an
unsigned type.

The only case where Py_UNICODE could become signed is via
a compiler that defines wchar_t to be signed -- rather unlikely.
