U+FC89 "ﲉ" Arabic Ligature Meem with Meem Final Form Unicode Character

U+FC89 "ﲉ" Arabic Ligature Meem with Meem Final Form is a typographic character used in the Arabic script to represent a two-letter ligature where the letter meem is written twice in a combined form, specifically in its final position within a word. This ligature is part of a block of Arabic presentation forms that were encoded to support advanced text rendering for legacy fonts and certain document formats, allowing for the graphical representation of a double meem that appears more compact or stylistically unified than writing two separate meem characters. In modern digital text processing, U+FC89 is generally considered a deprecated presentation form, as contemporary Unicode-based systems and fonts handle such ligatures automatically through shaping rules, making the character mostly relevant for historical or compatibility purposes.
