#ifdef HAVE_USABLE_WCHAR_T
memcpy(unicode->str, w, size * sizeof(wchar_t));
#else
...
#endif
I understand this code as: sizeof(wchar_t) == sizeof(Py_UNICODE). If I
misunderstood the code, it's a a heap overflow :-) So there is no not
conversion from UTF-32 to UTF-16 using memcpy if HAVE_USABLE_WCHAR_T is
defined, right?

PyUnicode_FromWideChar() is not a public API. Should I write a function in
_testcapi?
