Wow. That's short and to the point. I like it.

A few issues:

(1) It doesn't seem to be reversible:

>>> '© and many more...'.decode('latin-1')
u'© and many more...'

What should I do instead?


(2) Are XML entities guaranteed to be the same as HTML entities?


(3) Is there a way to find out at runtime what encoders/decoders/error
handlers are available, and what they do? 


Thanks,
