What 𞺫 means
It is Arabic lam in a distinct mathematical style. The formula's notation gives it a role; the glyph alone names no fixed quantity or operation.
Its letterforms reach back to manuscripts
Arabic mathematics used styled letters in manuscripts and print. Unicode's sample shapes draw on a manuscript copy by mathematician Ibn al-Banna (1256–1321); similar forms appear in 16th-century Maghrebi (northwest African) manuscripts.
Separate math characters preserve a chosen style instead of joining like ordinary Arabic letters. Arabic- and Persian-script math handbooks across the Middle East, Libya, and Algeria use this notation.

1Why does 𞺫 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.
