Good example. I believe adding ", encoding='latin-1'" to open() is
sufficient. (And from your response elsewhere to Stephen, you seem to
know that.) This should be in the tutorial if not already. But in
reference to what I wrote above, knowing that magic phrase is not
'knowledge of unicode'. And I include it in the 'not much more
knowledge' needed for Python 3.
