these work fine here.
jasen=# select htmlent('‘ ’ “ ” …');
htmlent
-----------
‘ ’ “ ” …

I see a pipe symbol '|' is that what you wrote?

I was under a mistaken impression of the encoding of HTML numeric
entities.

it works here because server_encoding is UTF8;
to check do this.
show server_encoding;show client_encoding;
it looks like you's need to convert the numbers to utt-8 in a bytea
type and then use convert to translate then to your preferred encoding
(appears to be win125x)
postgresql8.3 appears to provide no way to generate UTF-8 in a bytea
type so if you can't use a utf-8 encoding for your database you'll
have to write your own.
