Good work but we can clean that up a bit. If i may ... 

use strict;
use warnings;
use HTML::Template;
use HTTP::Server::PSGI;
use Encode;

my $tmpl = HTML::Template->new( filehandle => \*DATA );
$tmpl->param(
    foo => Encode::decode( 'UTF-8', "\xe2\x99\xa5" ),
    bar => "\x{2665}",
    baz => chr(9829) x 10,
);

my $app = sub {
    return [
        200,
        [ 'Content-Type' => 'text/html; charset=UTF-8', ],
        [ Encode::encode( 'UTF-8', $tmpl->output ) ],
    ];
};

my $server = HTTP::Server::PSGI->new(
    host    => "127.0.0.1",
    port    => 9091,
    timeout => 120,
);
$server->run($app);
