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
