AFAICR it does.

As soon as I find the time, I'll try to do a different version of

the patch, i.e. one that doesn't require such vast changes to
the C API: The string will still be passed as a
Py_UNICODE */int pair and the encoding as a char *.
Maybe the chances of inclusion into the Python core for this
new patch will be better. This patch has another advantage: for
well known error handling names (e.g. "xmlreplace" for encoding)
the replacement algorithm could be implemented directly in the
encoder/decoder for maximum performance.

Now the only remaining problem is time! :-/
