You can't safely do this anyway. Whether it's %s with a str and a unicode, or %s with a unicode and a str, *something* is going to have to be implicitly encoded or decoded, and if ascii doesn't happen to be the correct encoding then the result will be either an error or a silent failure. -- https://mail.python.org/mailman/listinfo/python-list
