Hey there,
I work with blind and deafblind people and started getting into Braille lately. The letters of the alphabet are arranged according to a system, the first ten letters make no use of the bottom spots, the next ten letters are the same with the bottom left spot and the remaining ones use both bottom spots - the letter W is an exception to this, using only the bottom right spot, which would technically be before the U. Does anybody have any trivia about this? Did the French sort their alphabet differently when Louis Braille developed his stuff? Did he "forget" the W and inserted it at a later point in development? Just curious, because all else is pretty logically built from my view with a little understanding of IT, language, maths, etc.
