[Koha] Empty PDF file when printing labels

[Franz Dietrich]

That is most likely the one... I was checking individual books to check 
it works at all but probably all of them had an encoding issue...

Would there be an error somewhere if it was an encoding issue? I could 
try to fix it even though I do not know any perl.

And thanks for the hint I did not find that bug yet!
