Gtk2-Perl is still returning UTF-8 data.

Platform: OS X 10.5 with Perl 5.10 and Gtk2-Perl 1.202, LANG=en_US.UTF-8.

Given:

#!/opt/local/bin/perl
use Gtk2 '-init';
my $window = Gtk2::Window->new();
my $button = new Gtk2::Button( "print" );
my $entry  = new Gtk2::Entry;
my $vbox = Gtk2::VBox->new (FALSE, 8);
$window->add($vbox);
$vbox->add($button);
$vbox->add($entry);
# perl bitches about multibyte characters unless you set UTF-8 on STDOUT
binmode STDOUT, ":utf8";
$button->signal_connect( "clicked",sub {
    my $word = $entry->get_text();
    my @word = split(//, $word);
    my $hexword = q();
    foreach my $letter ( @word ) {
        $hexword .= sprintf(q(0x%0x), ord($letter)) . q( );
    } # foreach my $letter ( @word )
    print qq|$word ( $hexword )\n|;
} );
$window->show_all();
Gtk2->main;

I can input 'test' and 'ÑÐÑÑ' (a string that needs two bytes per
character to encode), and both will be printed to STDOUT as UTF-8:

[manzana][brian ~]$ perl output.test.pl
test ( 0x74 0x65 0x73 0x74  )
ÑÐÑÑ ( 0x442 0x435 0x441 0x442  )

As you can see, the output is not 8-bit for the second input string.

Even changing locales to the locale you gave doesn't change the output;

[manzana][brian ~]$ LANG=en_US.ISO-8859-1 perl output.test.pl
test ( 0x74 0x65 0x73 0x74  )
ÑÐÑÑ ( 0x442 0x435 0x441 0x442  )

Do you have a complete example that shows your problem?

Thanks,

Brian
