Dear fellow monks,

I have an issue with MIME::Lite::TT::Html in that it does not properly handle umlauts (UTF-8 in general).

This is my sample code:

#!/usr/bin/env perl
use strict;
use warnings;
use MIME::Lite::TT::HTML;
use Encode;

my %params;

$params{umlaut} = 'fööbär';
Encode::_utf8_on($params{umlaut});

my %options= (
  INCLUDE_PATH => '.',
  ENCODING => 'UTF-8',
);

my $msg = MIME::Lite::TT::HTML->new(
          From        =>  'admin@example.com',
          To          =>  'frank@example.com',
          Subject     =>  'Your recent purchase',
          Template    =>  {
                              text    =>  'revsys.txt.tt',
                              html    =>  'revsys.html.tt',
                          },
          TmplOptions =>  \%options,
          TmplParams  =>  \%params,
);

binmode STDOUT, ':utf8';
print "Should be: ", $params{umlaut},$/;
print '-' x 79,$/;
print $msg->as_string;

And these are the templates:

revsys.txt.tt:
text: [% umlaut %]

revsys.html.tt:
<h1>[% umlaut %]</h1>
[download]

The output is:

Should be: fööbär

This is a multi-part message in MIME format.

As you can see: The Template output is just "fbr" and should be "fööbär".

Any advice? Did I do something wrong? Are there alternatives I should consider which can handle UTF-8?
