I get: (platform is Fedora 13, git tip, perl 5.10.1):

andrew=# CREATE OR REPLACE FUNCTION url_decode(Vkw varchar) RETURNS
varchar AS $$
andrew$# use strict;
andrew$# use URI::Escape;
andrew$# return uri_unescape($_[0]); $$ LANGUAGE plperlu;
CREATE FUNCTION
andrew=# select url_decode('comment%20passer%20le%20r%C3%A9veillon');
url_decode
------------------------------
comment passer le réveillon
(1 row)

andrew=#

which makes it look like we might have some double escaping going on
here, but at least I don't get nothing :-)

Further experimentation shows even more weirdness. There's definitely
something odd about the utf8 handling. Will dig further.
