Actually, given recent discussion I think that test should just be
removed from json.c. We don't actually have any test that the code point
is valid (e.g. that it doesn't refer to an unallocated code point). We
don't do that elsewhere either - the unicode_to_utf8() function the
scanner uses to turn \unnnn escapes into utf8 doesn't look for
unallocated code points. I'm not sure how much other validation we
should do - for example on correct use of surrogate pairs. I'd rather
get this as right as possible now - every time we tighten encoding rules
to make sure incorrectly encoded data doesn't get into the database it
causes someone real pain.
