Joining Group - Reversed Pe

Reversed Pe is a specific value in the Arabic script shaping system, denoting a joining group that behaves like the letter Pe but with its visual form mirrored horizontally. This group is used for characters that are typographically equivalent to a reversed Persian or Arabic Pe, often found in languages like Sindhi or other regional scripts where a distinct glyph is needed to represent a voiced bilabial or labiodental sound. Characters assigned to this group follow the same joining rules as Pe, meaning they connect to preceding and following letters in a cursive manner, but their isolated and initial forms are flipped along the vertical axis. This value ensures that such letters maintain proper contextual shaping without breaking the visual flow of connected text, while clearly distinguishing them from the standard Pe in both appearance and phonetic identity.
