plperlu problem with utf8

Hi there,

below is the problem, which I don't have when running in shell. The database is
in UTF-8 encoding.

CREATE OR REPLACE FUNCTION url_decode(Vkw varchar) RETURNS varchar AS $$
use strict;
use URI::Escape;
return uri_unescape($_[0]);
$$ LANGUAGE plperlu;
CREATE FUNCTION
Time: 1.416 ms
select url_decode('comment%20passer%20le%20r%C3%A9veillon');
url_decode
------------------------------
comment passer le rveillon
^
non-printed

Regards,
Oleg
