Python LaTeX codec?

[David Eppstein]

Does anyone have an implemented Python codec for converting between 
unicode and LaTeX markup?  E.g. I'd like 'ï' to be converted to '{\"\i}' 
and vice versa.  Preferably including at least the Latin Extended-A 
characters as well as the basic Latin-1 Supplement.

If not, anyone with experience writing Python codecs have any advice on 
how to do this?
