Braille pattern dots 3-6-7

No single reading follows from this cell alone. A language's Braille table may assign it a letter, punctuation mark or contraction; another may leave it unused. A technical code can set its own reading. Unicode keeps the dot pattern as a text character.

Braille grew from earlier raised-dot writing. Charles Barbier's 1815 account describes a system for blind readers; later accounts say he first designed it for soldiers to read in darkness, a disputed origin story. In the nineteenth century, Louis Braille refined tactile dots into compact cells read by one fingertip.
