First of all many thanks to @Richard Jedlička for this great module. It does exactly what I was looking for, unfortunately I have a problem with the generated thumbnails: German umlauts are simply not displayed. In the ImageMagick documentation I can't find any hint and can only assume that it is somehow related to Ghostscript?
Maybe someone of you already had the same problem found and a solution?
Many thanks in advance!
Cheers,
Florian
