All of the examples I can think of either: - poke into PyUnicodeObject's internals, - call a Python function that exposes Py_UNICODE or PyUnicodeObject I'm explicitly trying to protect those two cases. It's quite possible that I'm missing something, but I can't think of any other unsafe way for a C extension to convert a Python Unicode object to a byte string. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue8654> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
