U+FE91 "ﺑ" Arabic Letter Beh Initial Form Unicode Character

U+FE91 "ﺑ" Arabic Letter Beh Initial Form is a presentation form of the Arabic letter "Bāʼ" (ب), specifically designed to appear in the initial position of a word, where it connects to the following character on its left within the cursive Arabic script. This encoded variant is part of the Arabic Presentation Forms-B block and exists primarily for compatibility with older text processing systems that relied on explicit positional glyphs, as modern Unicode rendering engines typically select the correct initial form automatically from the standard letter "ب" (U+0628) based on contextual shaping rules. Its usage ensures that text appears with the appropriate ligature and stroke when displayed in environments that lack complex text layout support.
