that is not UTF8.
the UTF8 representation for 'ë' in SQL is e'\xC3\xAB' or chr(235)
your input appears to be encoded in LATIN-1 (or possibly 8859-13)
I think you'll need to write a function.
here, where I have database encoding UTF8 this appears to work as you
desire.
CREATE or replace FUNCTION htmlent(inp text) returns text as
$f$
DECLARE str text;
BEGINstr= regexp_replace(quote_literal( inp) ,$$&#(\d+);$$ ,$$'||chr(\1)||'$$
,'g');execute'select '||str into str;return str;
END
$f$
LANGUAGE PLPGSQL;
select htmlent('de patiënt niet');
probably the above should be expanded to handle named entities
like '&' too.
characters outside of the LATIN-1 space are not handled
but aparently this is what you want.
