U+FE79 "ﹹ" Arabic Damma Medial Form Unicode Character

U+FE79 "ﹹ" Arabic Damma Medial Form is a presentation form of the Arabic diacritic damma, specifically designed for the medial position within a word to indicate the short vowel /u/. Unlike the stand-alone damma (U+064F), this character is part of the Arabic Presentation Forms-B block and is used in complex text rendering, often for historical or stylistic contexts, where it appears as a small, comma-like shape positioned over the median letter to ensure proper typographical alignment in fully connected Arabic script. It is typically employed in legacy systems or specialized fonts rather than in modern Unicode text, where the regular damma is preferred for simplicity.
