Joining Group - Manichaean Teth

Manichaean Teth is a joining group value that represents the letter Teth as it appears in the Manichaean script, an ancient writing system used for the Manichaean religion. In text shaping and rendering, this value determines how the glyph connects to adjacent letters, specifically indicating that Teth takes a form with both a rightward and a leftward joining behavior, allowing it to link with letters on either side within a word, while also accounting for its distinct cursive style. This ensures that when Manichaean text is displayed, the Teth letter correctly adapts its shape according to its position, such as initial, medial, or final, to maintain proper ligature and visual continuity with neighboring characters in the script.
