Cannot encode double & single quote " and ' using htmldb_util.url_encode()

Question

Hello,
I'm using HTMLDB 1.5.0.00.33 on Oracle 9.2.0.6 database. The data(a sql query that populates the report page) that I want to pass as part of URL string contains special characters like #, $, % and quotes " or '. I'm using htmldb_util.url_encode() to encode the data and it works fine for special characters except for " & '. Can someone please help in this? Below sql query shows that.
SQL>select htmldb_util.url_encode('A%"#') from dual;
HTMLDB_UTIL.URL_ENCODE('A%"#')
A%25"%23
1 row selected.
Thanks

Shashin,
You could try using the UTL_URL.Escape function with the escape_reserved_chars parameter set to TRUE. That should encode the reserved characters.
See the documentation here: http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_url.htm#sthref15935
If you want to call it from a SQL statement, you'll need to wrap it in a function like this:
function MyURLEscape(URL varchar2) return varchar2 is
   Result varchar2(4000);
begin
   Result := UTL_URL.Escape(URL, TRUE);
   return(Result);
end MyURLEscape;
