You and others are welcome to profile the code looking
for opportunities to optimize even more, but I'd be surprised if you
find something significant.  In particular, UTF-8 decoding validates
as part of the decoding loop, and is already optimized for ASCII, so
it will be interesting to see what kind of gains we could have in
json_make_string by testing for ASCII up front.


I wonder what conclusions you're going to make from the current results.
