Braille dots 2-3-4-7

Start with their positions in an eight-dot cell. A Braille cell is a small arrangement of raised dots read by touch. Viewed from the reading side, its left column is numbered 1, 2, 3, 7 from top to bottom; the right is 4, 5, 6, 8. In ⡎, the lower three positions on the left and the top position on the right are filled.

The name “Braille 2347” describes that arrangement, not a universal letter. Eight-dot Braille extends the six-dot cell with two positions at the bottom, allowing more combinations. To translate ⡎ in a passage, identify the language and Braille code being used; its Unicode identity alone does not assign a reading.

On an ordinary screen, ⡎ is a visible text character, not a raised surface. A refreshable Braille display uses movable pins to make dot patterns readable by touch.
