I've been trying to test GD::Graph and Unicode using a code snippet from bioportal.weizmann.ac.il but either I'm doing something wrong or GD::Graph does not support Unicode. Hopefully, you can spot my mistake. 
use utf8;
use GD::Graph::linespoints;

@data = ( 
    ["1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th"],
    [undef,  52,  53,  54,  55,  56,  undef,  58,  59],
    [60,  61,  61,  undef,  68,  66,  65,  61, undef],
);

$my_graph = new GD::Graph::linespoints( );
$my_graph->set( 
        x_label => 'X Label',
        y_label => 'Y label',
        title => 'A Lines and Points Graph',
        y_max_value => 80,
        y_tick_number => 6,
        y_label_skip => 2,
        markers => [ 1, 5 ],
);

my $ustring1 = "\x{263A}";
my $ustring2 = "\x{263A}";

$my_graph->set_legend( $ustring1, $ustring2 );
my $gd = $my_graph->plot(\@data);

open(IMG, '>uni.gif') or die $!;
binmode IMG;
print IMG $gd->gif;
close IMG;
