1947 Roswell, New Mexico. They found Klingons!

I'm wondering if Esperanto is recognised. If so, Klingon appears to be equally valid. Both are artificial languages.
Also, Klingon was apparently at one point the world's fastest-growing language. Shakespeare plays have been translated into Klingon, and there's even a Klingon Language Institute in Pennsylvania.

There's also an opera which ran in the Netherlands and Germany a few months ago: link.

Hah, that's hilarious.

Maybe you can use this keyboard with it:
