U+FE78 "ﹸ" Arabic Damma Isolated Form Unicode Character
Unicode Version 17.0
ﹸ
U+FE78 "ﹸ" Arabic Damma Isolated Form is a presentation form of the Arabic diacritic mark known as Damma, which indicates the short vowel /u/ in the Arabic script. This specific isolated form is encoded separately from the standard Damma (U+064F) to allow for precise typographic and calligraphic rendering, particularly in contexts like the Quranic text or advanced typesetting systems where a distinct shape is needed when the vowel sign appears on its own or in isolation. It appears as a small, looped glyph resembling a miniature comma or curl placed above or attached to Arabic letters, though its isolated form is typically used only in specialized typographic environments rather than ordinary digital text.
