Joining Group - Manichaean Daleth

Manichaean Daleth is a joining group value that identifies a specific script character’s behavior in cursive text shaping, specifically the Manichaean letter daleth, which corresponds to the fourth letter of that alphabet. This value denotes that the character belongs to a joining group where its initial, medial, and final forms connect in a predictable manner, following the right-to-left script’s rules for ligature and spacing. It ensures that when the daleth appears in a word, it interacts correctly with adjacent characters, particularly influencing how preceding and following letters are joined or broken. This classification helps render Manichaean text accurately across digital fonts, preserving the script’s visual continuity and legibility without requiring per-character manual adjustments.
