[Python-Dev] unicode/string asymmetries

Unfortunately, that is quite difficult. Python does not guarantee that
the internal representation of Unicode strings uses wchar_t, so such a
conversion definitely requires explicit memory management. This is
unlike plain strings, which do guarantee that the internal
representation is char[].
