U+FD3D "ﴽ" Arabic Ligature Alef with Fathatan Isolated Form Unicode Character

U+FD3D "ﴽ" Arabic Ligature Alef with Fathatan Isolated Form is a typographic ligature found in the Arabic script block that represents a specific calligraphic combination of the letter alef (ا) with the fathatan diacritic (two fathas) appearing as a single, connected glyph. This character is designed for use in high-quality text rendering such as Qur'anic and religious manuscripts, where it helps maintain visual consistency and aesthetic flow by merging the base letter with its double vowel marking into a compact isolated form. It is distinct from the separate sequence of an alef followed by a fathatan, as it exists as a predefined encoded unit to simplify composition in systems that support advanced Arabic typography.
