(Serhiy, did you miss uploading the new patch?)
Regarding the names, we may need to think about the use cases a bit more
explicitly to clarify that in terms of the Python codecs API rather than
expecting folks to understand the underlying representation. In the case of
handling lone surrogates and escaped surrogates, what about:
rehandle_surrogatepass(data, errors="strict")
rehandle_surrogateescape(data, errors="strict")
That is, we know we have data that was decoded with either surrogatepass or
surrogateespace (respectively) as the error handler, and we want to process the
results of that with a different error handler.
I believe those two would be enough to address the specific cases this issue
was raised to cover, so it may make sense to file a separate issue to discuss
the use cases for the custom astral handling.
Since astrals aren't actually errors in the first place, that could become:
handle_astrals(data, errors="strict")
As in "pass every astral code point in this string through the named error
handler".
The astral -> surrogate pair and surrogate pair -> astral converters do sound
potentially interesting, but as noted above, I think they may call for a
separate issue that better explains the specific use cases.
