Change %c format specifier for PyArg_ParseTuple() so that it accepts
a unicode character (an int * must be passed as the argument).
Change %c format specifier for Py_BuildValue() so that it outputs
a unicode object.
Fix datetime.datetime.isoformat(), so that it works if sep is
a unicode character > U+00FF.
