[New-bugs-announce] [issue17906] Add a string error handler to JSON encoder/decoder

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Inspired by simplejson issue [1] which is related to standard json module too. JSON parser 3.3+ and wide builds of 3.2- raise an error on invalid strings (i.e. with unpaired surrogate), while narrow builds and some third-party parsers. Wide builds are right, such JSON data is invalid. However it will be good to be optionally more permissive to input data. Otherwise it is not easy process such invalid data.

I propose to add an "error" parameter to JSON decoder and encoder with the same meaning as in string decoding/encoding. "strict" is default and "surrogatepass" corresponds to narrow builds (and non-strict third-party parsers).
