Yes, that commit looks broken. If you convert from text to JSON you
should get a JSON string equivalent to the text you started out with.
That commit departs from that in favor of allowing \uXXXX sequences in
the text being converted to turn into a single character (or perhaps
an encoding error) after a text->json->text roundtrip. Maybe I
haven't had enough caffeine today, but I can't see how that can
possibly be a good idea.
