That's always been the case.

I think that would be too big a break from past practice --- the
operative word being "break", because in LATINn character sets chr/ascii
work just fine.

I wouldn't object to introducing some sort of unicode_chr/unicode_ascii
function pair that translates to/from Unicode code points regardless of
the DB encoding. But that smells way more like a new feature than
plugging a hole, so I suggest it should wait for 8.4.
