Joining Group - Manichaean Beth

Manichaean Beth is a joining group value that categorizes the letter Beth as it appears in the Manichaean script, an ancient writing system used for religious texts. This value indicates that Beth typically connects to both preceding and following letters in cursive script contexts, following the joining behavior rules for that script. Specifically, it means the character can form initial, medial, or final forms depending on its position within a word, but it does not have a dual-joining or isolated-only nature. This classification helps text shaping engines render the correct glyph variant when displaying Manichaean words, ensuring proper visual continuity and legibility.
