Weird behaviour with strings and accents

[Cyril SCETBON]

I'm using Modperl 2.0.2 with apache 2.0.55 and modperl is doing 
something wrong with my string :

my $var="à présent protégé";
warn Dumper [$var];
my $var="à présent protégé".$login;
warn Dumper [$var];
$VAR1 = [
          'à présent protégé'
        ];
$VAR1 = [
          "\x{c3}\x{a0} pr\x{c3}\x{a9}sent
prot\x{c3}\x{a9}g\x{c3}\x{a9}login774"
        ];

__END__;

The accents are no more printed correctly !!

Any idea ?
