Correct. So it seems this needs to be fixed in makeunicodedata.py already. This was not the case with earlier versions of Unicode (which never had a mapping to the same code point). The logic for using deltas is also incorrect, so makeunicodedata.py needs to be fixed anyway. _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4971> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
