Joining Group - African Noon

African Noon is a joining group designation for the Arabic letter noon, specifically the variant used in African languages such as Hausa and Fulfulde, where it represents a palatal or velar nasal sound like the “ng” in “sing”. This group defines how the character connects to adjacent letters in cursive scripts, ensuring that the African noon maintains its distinct initial, medial, final, and isolated forms without being confused with the standard Arabic noon. It enables proper shaping and ligature behavior in digital text, preserving the phonetic and orthographic integrity of languages that use this modified letter within an Arabic-derived writing system.
