U+FEB9 "ﺹ" Arabic Letter Sad Isolated Form Unicode Character

Unicode Version 17.0

U+FEB9 "ﺹ" Arabic Letter Sad Isolated Form is a typographic variant of the Arabic letter "ص" (Sad), designed specifically for use in cursive Arabic script when the letter appears alone or in an isolated position within a word. This character represents the prescriptively correct form for initial or standalone contexts in many traditional calligraphic styles, such as in the beginning of a word or when it is not connected to a preceding or following letter. In modern Unicode text, it is part of the Arabic Presentation Forms-B block, which encodes these positional shapes to support historical and aesthetic rendering requirements, though contemporary Arabic fonts typically handle such contextual forms automatically through OpenType shaping, making explicit use of this character less common for standard digital text.
