Yes! Thanks very much -- I looked at that page several times and  
missed regexp_replace.

Here is an example:

=== psql 3 ===
select regexp_replace('©«¡®£§¼½¾¿ ÀÉÌÓÙÝ àéìóùý  
āŹźŻżŽž ∧∨ wxyz', '[^\\u0000-\\u00FF]', '?', 'g');
              regexp_replace
------------------------------------------
©«¡®£§¼½¾¿ ÀÉÌÓÙÝ àéìóùý ??????? ?? wxyz
(1 row)
