In terms of names, this is a cosmopolitan moth. Its English name derives from the resemblance of its strikingly prominent dark markings to the Hebrew letter Nun. Linnaeus added a typeface element to this by calling it Orthosia gothica. There's another UK moth called the Setaceous (or bristly) Hebrew Character which has a similar though slightly less distinctive mark. But they are not related.
I am just old enough to remember a few copies of our Deutsches Leben textbook at school being printed in Fraktur - the German Gothic or Blackletter typeface which was inflicted on that poor country in the name of culture for a large part of the 20th century.
