[Python-ideas] Add "namereplace" error handler

[Amaury Forgeot d'Arc]

It's easy to implement in Python code:

import codecs, unicodedata

def namereplace_errors(exc):
    replace = "\\N{{{}}}".format(
        unicodedata.name(exc.object[exc.start]))
    return replace, exc.start + 1

codecs.register_error('namereplace', namereplace_errors)

> b'\\u22121'
> >>> '-1'.encode('ascii', 'namereplace')
> b'\\N{MINUS SIGN}1'

> In some cases such representation is more readable.

> What are you think about this? Are there suggestions for better name?
