Braille pattern, dots 1–4 and 8

Three on the left, two on the right. An eight-dot Braille cell has two columns of four positions. From the reading side, the left column is numbered 1, 2, 3, 7 from top to bottom; the right is 4, 5, 6, 8.

In ⢏, the top three left positions and the top and bottom right positions are filled. Positions 5, 6 and 7 are empty. “Eight-dot Braille” describes the available positions, not the number of dots filled in this character.

What does it mean in Braille?

The Braille code determines its reading. Braille is a system of raised dots that blind readers read by touch. It represents different languages and also supports notation such as mathematics and music. Unicode records this cell’s dot pattern; it does not assign it a universal letter or word.

Louis Braille developed his six-dot system in the 1820s, drawing on Charles Barbier’s raised-dot “night writing.” Braille’s 1829 publication described writing and music. Eight-dot Braille extends the six-dot cell with two positions underneath.

A character displayed on an ordinary screen is only a visual representation. Tactile reading requires physical raised dots, for example on embossed paper or a refreshable Braille display; their size and spacing matter.
