You are using non-ASCII characters directly in the source code.  Do you
have a proper encoding declaration at the top of the file?

This certainly looks weird.  It seems to be incorrectly encoded *twice*.

Specifying the source encoding correctly ought to work.

To help search for the cause of the bug (or bugs) you may want to
try title = _(u"Nosso n\u00FAmero") temporarily.

FWIW the usual way is to use English titles in the source code and
provide a .po file with translations.  I'm not sure how to hook that up
through Five.

multicast/broadcast UDP, and extremely odd XML) is a must-read for fans of
unnatural and baroque network protocols.
