1. It isn't "Python's yenc". Consider directing your question to whoever (if anyone) is maintaining whichever third-party module you are talking about. 2. Consider using a tool that will display what is going on in characters and hex e.g. http://linux.about.com/library/cmd/blcmdl1_hexdump.htm -- http://mail.python.org/mailman/listinfo/python-list
