That wasn't actually the case. The overwriting of memory was really independent of the error in surrogate processing, and can be fixed independently.

I think this is unimportant enough to just accept this bug for Python 2.2.x. If people ever run into the problem, well: just don't do this. Unpaired surrogates will be entirely in Unicode 3.2.

The memory-overwriting problem can be fixed independently, e.g. with
