PS: One more imortant thing I should add: Just like sign language, Braille is NOT
'universal'.
Yes, Braille is used all over the world, but which characters, accents, etc are assigned to which dot pattern may be very different from language to language.
My comments upthread re #contractedBraille apply to #UEB, aka Unified English Braille, now in use across (all?) English-speaking nations.
6 dots = 64 possible one-cell characters
