I'd also weight in the fact that this is a change of behaviour since the
introduction of unicode in 2.0, and it's break real-world applications (as
demonstrated by this thread). I think Python ought to revert to the previous
behaviour and, in case there's interest, the discussion moved to the py3k list.
