[Python-Dev] PEP 383 update: utf8b is now the error handler

["Martin v. Löwis"]

> The error handler for undoing this operation (ie. when converting
> a Unicode string to some other encoding) should probably use the
> same name based on symmetry and the fact that the escaping
> scheme is meant to be used for enabling round-trip safety.

Could you please familiarize yourself with the implementation
before commenting further?

Thanks,
Martin
