So how would I write a codec that converts all characters to Latin-1,
and converts those out of latin-1 to &#xxx; (instead of the
replacement character)? I'd need knowledge about what character are in
Latin-1, and I'd need to do conversion on a character-by-character
basis, right? And I can't possible use any of the _codecs helper
functions?

This is certainly feasible if I want it for a single character set,
but now if I want to do it wholesale for the entire set of character
sets supported by Python 2.0.
