Joining Group - Manichaean Taw

Manichaean Taw is a joining group value that applies to the Syriac letter Taw in the Manichaean script, used primarily in liturgical texts. This value indicates that the letter connects to both preceding and following characters in a cursive joining system, following a right-to-left directionality. Specifically, it designates that Taw can form a dual-joining behavior, linking on its right side to the previous letter and on its left side to the next letter, while also maintaining a distinctive medial or final form depending on context. The value ensures that when Taw appears in a word, it does not break the cursive flow, allowing for proper shaping and ligature formation alongside other joining groups like Aleph or Beth. This behavior is essential for accurate rendering of Manichaean script in digital typography, preserving the visual continuity and phonetic integrity of the text.
