You should check the encoding of stdout when running from django, I suspect that it is plain ascii rather than utf-8 which is what you are probably getting when running standalone. Check sys.getdefaultencoding().

Note that this has nothing to do with django, just the way stdin/stdout are set up depending on how your script is running.
