But character set issues also make it impossible to provide such a
translation routine: the current party line is that the encoding of
8-bit strings is unknown and that only ASCII can be assumed.

xml.sax.saxutils.escape() is a generalization of cgi.escape() -- read
the source (Lib/xml/sax/saxutils.py). It allows you to specify
additional things to be replaced by entities by passing in a
dictionary mapping chars (or strings) to entities.
If you know that you are dealing with Latin-1, you could use the table
in htmlentitydefs.py to construct a table.
