Braille pattern with dots 1-2-5-6

The Braille code decides its reading. Unicode preserves the six-dot arrangement, not one universal word. In contracted English Braille, ⠳ is the contraction for “out.”

Charles Barbier presented an earlier raised-dot system, known as “night writing,” at a school for blind students in Paris in 1821. Louis Braille published a smaller six-dot system in 1829, designed for reading and writing by touch.
