Can this be converted to english as per original OSTICKET, i think this is the problem section:
$name="Name: ".$ticket->getName();
$mail="E-Mail: ".$ticket->getEmail();
$betreff="Subject: ".$ticket->getSubject();
$datum="Date: ".$ticket->getCreateDate();
$nachricht_roh=$msg_row;
$nachricht = str_replace("\n\r", "$pdf->Ln", $nachricht_roh);
$nachricht = str_replace('„', '"', $nachricht_roh);
$nachricht = str_replace('•', '-->', $nachricht_roh);
$nachricht = str_replace('€', ' Euro', $nachricht_roh);
$nachricht = str_replace('„', '"', $nachricht_roh);
