Correct.
The purpose of an error handler name is to indicate to the user
what it does, hence the use of verbs.
Walter started with "xmlcharrefreplace", ie. no space names, so
"surrogatereplace" would be the logically correct name for the
"replace with lone surrogates" scheme invented by Markus Kuhn.
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.
BTW: It would also be appropriate to reference Markus Kuhn in the PEP
as the inventor of the escaping scheme.
Even if only to give the reader an idea of how that scheme works and
why (the PEP on python.org currently doesn't explain this).
It should also explain that the scheme is meant to assure round-trip
safety and doesn't necessarily work when using transcoding, ie.
reading using one encoding, writing using another.
