Braille pattern dots 1-2-5-8

⢓ includes dot 8, so its reading depends on an eight-dot Braille code and the language; the pattern alone does not identify a universal letter or word. The familiar six-dot alphabet has no dot 8. Braille grew from Charles Barbier's raised-dot code for silent military communication in the early nineteenth century; Louis Braille reworked the idea in 1821 and had a compact six-dot system by 1824.
