Maybe something like this: 
#!/usr/bin/perl -l

BEGIN { $| = 1;}

use strict;
use warnings;
use utf8;
use Encode;
use CGI qw/:standard -utf8/;
use CGI::Carp qw/fatalsToBrowser set_message/;
$CGI::PARAM_UTF8 = 1;

BEGIN {
    sub handle_errors {
        my $msg = shift;
        print "<h1>There's a problem</h1>";
        print "<p>Cannot decode string: $msg</p>";
    }
    set_message(\&handle_errors);
}

my $q = CGI->new;
binmode STDOUT, ":encoding(UTF-8)";
my $referer_url = "@{[ $q->url ];}";
print $referer_url;
