Check that from actually inside your web script - os.environ["LANG"]
should be "en_US.UTF-8". If it isn't, then that may be where your
difference between web and interactive is, and so you'll need to be
more explicit about encodings.

It's common for background processes to have restricted environments,
sometimes with LANG=C or similar.
