#2798: PyArg_ParseTuple did not correctly handle the "s" code in case of unicode strings

Browse source 
with chars outside the 7bit ascii (s# was already correct).

This is necessary to allow python run from a non-ASCII directory,
and seems enough on some platforms, probably where the default PyUnicode encoding (utf-8)
is also the default filesystem encoding.
