U+061C "" Arabic Letter Mark Unicode Character
Unicode Version 17.0
U+061C "" Arabic Letter Mark is a special formatting character used in digital text to control the bidirectional display of Arabic script when it interacts with left to right text. It is classified as a format character and serves a similar purpose to the more common Arabic and right to left markers, helping ensure that adjacent Arabic letters connect and shape correctly according to cursive writing rules, even when they are separated by non Arabic characters or directionality changes. This invisible mark does not represent a spoken sound or letter by itself but is essential for maintaining proper visual order and ligature formation in mixed script contexts.
