How about this: we add a wchar_t codec to Python and the "eu#" parser
marker. Then you could write:

	wchar_t value = NULL;
	int len = 0;
	if (PyArg_ParseTuple(tuple, "eu#", "wchar_t", &value, &len) < 0)
                return NULL;
 
	...

	PyMem_Free(value);
	return ...

or, for 8-bit strings:

	char value = NULL;
	int len = 0;
	if (PyArg_ParseTuple(tuple, "es#", "latin-1", &value, &len) < 0)
                return NULL;
 
	...

	PyMem_Free(value);
	return ...

Is that symmetric enough ?
