replace single char for string using regexp_replace - Mailing list pgsql-general

I have to replace ; , " and ' chars in an string putting its correspondent
ascii value

I have a
Replace(Replace(Replace(Replace($$Text,with;On'It"$$,',','chr(59)'),';','chr(44)'),'"','chr(34)'),'''','chr(39)')
It works but I would like to call just one Replace.

I tried this but didn´t work
select
regexp_replace($$Text,with;On'It"$$,$$,|;|"|'$$,$$chr(59)|chr(44)|chr(34)|chr(39)$$,'g');
, -> chr(59)
; -> chr(44)
" -> chr(34)
' -> chr (39)
