ESCAPE

Returns a URL with illegal characters (and optionally reserved characters) escaped using the %2-digit-hex-code format

utl_url.escape(
url IN VARCHAR2 CHARACTER SET ANY_CS,
escape_reserved_chars IN BOOLEAN DEFAULT FALSE,
url_charset IN VARCHAR2 DEFAULT utl_http.get_body_charset)
RETURN VARCHAR2 CHARACTER SET url%CHARSET;

SELECT utl_url.escape('http://www.acme.com/a url with space.html')
FROM dual;

UNESCAPE

This function unescapes the escape character sequences to its original form in a URL, to convert the %XX escape character sequences to the original characters.

utl_url.escape(
url IN VARCHAR2 CHARACTER SET ANY_CS,
url_charset IN VARCHAR2 utl_http.get_body_charset)
RETURN VARCHAR2 CHARACTER SET url%CHARSET;

SELECT utl_url.unescape('http://www.acme.com/a%20url%20with%20space.html')
FROM dual;
