Yes, this is a problem I noticed the other day as well. A ticket,
assigned to me, is in order.

For the gory details, see http://twistedmatrix.com/trac/ticket/3847. The
short version is that digest authentication requires UTF-8 encoded input
and GTK sets Python's default encoding to UTF-8. Before these checks,
using non-ASCII characters in passwords would fail in some cases. As
both the session id and password can use the full range of unicode, it
makes sense to require that explicitly.
