What ⡚ means
Two dots sit on the left, two on the right. A Braille cell is a small grid of positions for raised dots, read by touch. In an eight-dot cell, the left column is numbered 1, 2, 3, 7 from top to bottom; the right is 4, 5, 6, 8.
In ⡚, the left column has dots in the second and fourth rows; the right has dots in the first and second rows. The third row is empty. Dot 7 puts this pattern beyond the traditional six-dot cell.
Does ⡚ stand for a particular letter?
It has no single letter value across all Braille codes. Braille is a system for writing by touch, not a separate language. Different languages and notations assign meanings to dot patterns. Unicode stores this pattern without assigning it a particular reading.
For a translation, keep the surrounding cells and identify the original language and Braille code. The name “2457” tells you which dots are present; it does not tell you how to pronounce them.

Worth knowing
- Louis Braille developed his six-dot system in 1824, drawing on Charles Barbier’s night-writing for military messages. Braille’s 1829 publication also included music notation.
- Eight-dot Braille adds positions 7 and 8 below the six-dot cell, allowing 256 patterns instead of 64, including the blank cell.
Questions people ask
1Can a font change which dots ⡚ contains?
No. Fonts can change dot size and spacing, making a dot harder to spot, but the encoded positions remain 2, 4, 5 and 7.
