Das Problem lässt sich nachstellen.

Um herauszufinden, in welcher Vorlagedatei der Fehler auftritt, muss man Debugging anschalten:

Code (perl): (dl )

use utf8;
use Template qw();
use Template::Constants qw(DEBUG_PROVIDER);
my $template = Template->new(DEBUG => DEBUG_PROVIDER);
$template->process('foo.tmpl', { x => '☺' });
__END__
[Template::Provider] creating cache of unlimited slots for [ . ]
[Template::Provider] _fetch_path(foo.tmpl)
[Template::Provider] searching path: ./foo.tmpl
[Template::Provider] _fetch(./foo.tmpl)
[Template::Provider] _load(./foo.tmpl, foo.tmpl)
[Template::Provider] _compile(HASH(0x142dc80), <no compfile>)
[Template::Provider] _store(./foo.tmpl, Template::Document=HASH(0x185e268))
[Template::Provider] adding new cache entry

Die Lösung des Problems liegt in der korrekten Ausgabekodierung, d.h. entweder muss der vierte Parameter in der Methode process gesetzt werden:

Code (perl): (dl )
1
2

$template->process('foo.tmpl', { x => '☺' }, \*STDOUT, { binmode => ':encoding(UTF-8)' })
    or die $template->error;


oder global:

Code (perl): (dl )
    STDOUT->binmode(':encoding(UTF-8)');


So funktioniert es:

Code (perl): (dl )
1
2
3
4
5
6

8

use utf8;
use Template qw();
my $template = Template->new;
STDOUT->binmode(':encoding(UTF-8)');
$template->process('foo.tmpl', { x => '☺' })
    or die $template->error;
__END__
