This is by no means meant to be an inclusive list.  I’ve not even mentioned many countries.  There are languages whose alphabets or ideograms, I have no knowledge of so I'm not even sure what to search for.  This is just a way for you to contact a group in your section of the world and potentially have them refer you to someone closer to you if you’re interested in racing pigeons.
