What ⣳ means
Its reading depends on the Braille code. Unicode 17.0 records dot shapes; language and technical codes assign their readings.
An eight-dot Braille computer display could distinguish characters a six-dot cell could not; extra dots could mark emphasis or cursor position. By the late 1980s, most refreshable displays had eight-dot cells.
Charles Barbier devised “night writing,” a raised-dot military code for soldiers’ messages after dark. Louis Braille encountered it in 1821; its 12-dot cell was hard to read at one touch, so he developed a six-dot code by 1824 and published it in 1829.
Technical Braille pattern; reading requires a code.
Decorative Braille text is not a translation unless checked against the intended code.
