Braille Pattern Dots 1–8

It has no single universal letter meaning. Braille patterns take their meaning from the code and reading context. Unicode preserves the dot arrangement without assigning it a translation, so an isolated ⣿ is best read as an all-dot pattern.

Braille's history starts with tactile writing. In 1786, Valentin Haüy produced tactile text using embossed print—raised marks a reader could feel. Charles Barbier presented raised-dot writing at the Paris school in 1821. Louis Braille refined it into a six-dot system by 1824 and published it in 1829. Eight-dot Braille builds on that six-dot arrangement by adding two positions.
