What 𞸞 means
A dotless Arabic letter form used in mathematical notation.
Arabic math draws on alphabet forms used for centuries in manuscripts and print, including Arabic and Persian writing. North African algebraic notation is attested by the late 12th century; later examples include mathematician al-Qalasadi in the 15th century and a copy finished in Istanbul in 1747, later found in Jerba, Tunisia.
Does the dot change its meaning?
No; the dot marks style, not a mathematical difference.
A 2006 technical note describes dotted and undotted forms as local choices, with documents using one style consistently. This character also stays unshaped: unlike ordinary Arabic letters, it does not connect to neighbors.

1Why does 𞸞 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
