Joining Group - Manichaean Twenty

Manichaean Twenty is a joining group value that defines the contextual shaping behavior of the Manichaean numeral twenty, a character used in the Manichaean script. This value ensures the letterform connects appropriately to adjacent characters within a word, following the cursive joining rules of the script. Specifically, it identifies the character as having a right-joining tendency, meaning it can connect to a following letter but not to a preceding one, thus affecting how ligatures and positional forms are rendered. In practical terms, this grouping helps text layout engines correctly display the numeral in its isolated, initial, medial, or final shape depending on its position, preserving the visual integrity of Manichaean writing. Without this precise classification, the numeral would be rendered with incorrect connections, breaking the script’s flow.
