U+FDAB "ﶫ" Arabic Ligature Dad with Hah with Yeh Final Form is a typographic ligature used in the Arabic script, representing a specific combination of the letters Dād, Ḥāʼ, and Yāʼ in their final positional form. This character is part of the Arabic Presentation Forms-A block, which encodes precomposed glyphs for improved text rendering in traditional calligraphy or justified typesetting. It appears at the end of a word and is primarily employed in classical or religious texts, such as the Quran, where such ligatures preserve historical scribal conventions and ensure precise character shaping for readability. While rarely used in modern digital typography, it remains supported for legacy and specialized applications in Unicode.
