32bit table is nice.


Would you please replace
https://github.com/BobSteagall/utf_utils/blob/master/src/utf_utils.cpp URL
with
https://github.com/BobSteagall/utf_utils/blob/6b7a465265de2f5fa6133d653df0c9bdd73bbcf8/src/utf_utils.cpp
in the header of src/port/pg_utf8_fallback.c?

It would make the URL more stable in case the file gets renamed.
