U+FC63 "ﱣ" Arabic Ligature Shadda with Superscript Alef Isolated Form Unicode Character
U+FC63 "ﱣ" Arabic Ligature Shadda with Superscript Alef Isolated Form is a typographic ligature used in the Arabic script that combines the shadda (a diacritic indicating consonant gemination or doubling) with a superscript version of the letter alef (the glottal stop), presented in its isolated form. This character represents a specific orthographic convention where the shadda and a small, raised alef are merged into a single graphical unit, often employed in Quranic text or formal Arabic writing to denote a geminated consonant followed by a long vowel sound that originates from a historical alef. As part of the Arabic Presentation Forms-A block, this character is primarily intended for compatibility with legacy encoding systems and is not typically used for modern interactive text input, but it serves a specialized role in preserving the visual fidelity of certain classical calligraphic styles.
