Joining Group - Manichaean One

Manichaean One is a joining group value used to define how the letter shaped like the numeral “1” behaves in connected scripts, specifically within the Manichaean alphabet. When this character appears in text, it takes a non-joining form, meaning it does not ligate with letters on either side, standing alone even in cursive contexts. This behavior is distinct from other joining groups that create bidirectional connections, ensuring the Manichaean One retains its isolated visual identity for accurate rendering and reading.
