JavaFan has offered a good alternative approach to solve your problem.

I thought that I'd point out a simpler way to display the contents of your hash, using Data::Dumper:

use Data::Dumper;
print Dumper(\%hash);

which prints:

$VAR1 = {
          'Remove a document from the knowledge base' => 'Dokument aus
+ der Knowledge Base entfernen',
          'Document Expired' => 'Dokument abgelaufen',
          'Promote document retirement' => 'Dokument deaktivieren',
          'Retire a document' => 'Dokument deaktivieren'
        };
