U+FE84 "ﺄ" Arabic Letter Alef with Hamza Above Final Form is a presentation form of the Arabic letter alef with a hamza diacritic placed above it, specifically designed for use in the final position of a word during typographic rendering. It represents the glotal stop combined with a long vowel sound, commonly transcribed as "ʔa" or similar, and appears in Arabic script when the letter is connected to a preceding character but has no letter following it. This variant ensures proper shaping and legibility in complex text layouts, particularly in systems requiring contextual glyph selection for cursive scripts like Arabic.
