U+FC61 "ﱡ" Arabic Ligature Shadda with Damma Isolated Form Unicode Character

Unicode Version 17.0

ﱡ

U+FC61 "ﱡ" Arabic Ligature Shadda with Damma Isolated Form is a presentation form character used in the Arabic script to represent the combination of the shadda diacritic, which denotes gemination or doubling of a consonant, together with a damma, which indicates the short vowel "u," presented in an isolated visual form. This ligature is part of the Arabic Presentation Forms-A block in Unicode, designed specifically for compatibility with legacy text processing systems that required precomposed glyphs for such combinations, rather than for standard modern typing where separate diacritics are typically combined dynamically. Its use ensures correct display in contexts where the shadda and damma appear together over a single consonant character, preserving orthographic accuracy in Arabic calligraphy and traditional typesetting.
