U+206D "" Activate Arabic Form Shaping Unicode Character

U+206D "" Activate Arabic Form Shaping is an invisible, or "default ignorable," control character defined in the Unicode Standard. Its intended function is to signal to a text rendering engine that it should apply the rules of Arabic script shaping to the surrounding text, ensuring that Arabic letters take their correct initial, medial, final, or isolated forms depending on their position in a word. This character is part of a set of bidirectional and shaping controls designed for complex text layout, though it is rarely implemented or supported in modern software, and much of its usage has been deprecated or replaced by better-defined mechanisms within the Unicode Bidirectional Algorithm.
