Summary: PyArg_ParseTuple("u") inconstency

Initial Comment:
PyArg_ParseTuple behaves strangly with the format
character "u" when a plain string is passed as the
argument. This seems to perform the conversion
value.decoded("utf-16"), which is very surprising and
inconsistent with the behaviour of the python
expression unicode(value) with is equivalent with
value.decode("ascii").

The current behaviour will confuse users that pass
plain strings to extension functions expecting unicode
arguments.

Why is the current beahviour surprising ? The "u" parser
marker reads a buffer like object and interprets it
as Py_UNICODE array. It is very different from
what unicode(value) does. The "es" marker takes
care of unicode(value, encoding) kind of conversions.
