Out of curiosity, I looked it up, and there are braille versions of many alphabets:

I wonder how many blind multilinguists exist (that can read braille in multiple languages) . I imagine there's a lot of character collisions between different braille alphabets, but I suppose it wouldn't be any more difficult than (visually) reading, say, English and Spanish, which have virtually identical alphabets.
