Which is correct, the output for a Python 3.X WSGI application must be a stream of bytes and cannot be Unicode. See: http://www.python.org/dev/peps/pep-3333/ BTW, make sure you don't pay too much attention to: http://code.google.com/p/modwsgi/wiki/SupportForPython3X It is out of date. The mod_wsgi in source code repository is more closely aligned with final WSGI PEP 3333 and is more strict than what the wiki page describes. Adhere to WSGI PEP 3333 and code will still work on mod_wsgi.
