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