Armenia has its own alphabet with 39 letters. It was made around year 400AD and is nothing like our latin letters.
Another special thing is that they have a open air exhibition of the letters next to a memorial.
The U in the left center is S , my letter, that is how I know it, I actually bought one! Alittle to the right for the U there is a U with a little piece extra top right. That means this is a M. Logic, hardly!
