The Py_UNICODE type is still supported but deprecated. It is always
defined as a typedef for wchar_t, so the wstr representation can double
as Py_UNICODE representation.

It's too bad this isn't initialised by default, though. Py_UNICODE is the only representation that can be used efficiently from C code and Cython relies on it for fast text processing. This proposal will therefore likely have a pretty negative performance impact on extensions written in Cython as the compiler could no longer expect this representation to be available instantaneously.
