Actually, that would be fine, and Bob's right that this is a non-issue
with ensure_ascii=True (the default).  His change upstream seems good
for the ensure_ascii=False case.

To be complete, this is what I meant:

>>> s = '{"JSON":"ro
cks!"}' # this string has a literal U+2028 in it
>>> s

>>> import json
>>> json.dumps(s) # fine by default

>>> json.dumps(s, ensure_ascii=False) # not fine with ensure_ascii=False
