U+0889 "ࢉ" Arabic Letter Noon with Inverted Small V Unicode Character

U+0889 "ࢉ" Arabic Letter Noon with Inverted Small V is an extension to the Arabic script, designed to represent a specific phonetic sound found in some languages that utilize the Arabic alphabet, particularly in African languages such as Fulfulde (Fula). Its glyph combines the base shape of the Arabic letter noon with an inverted small V-shaped diacritic above it, indicating a separate consonantal value distinct from standard noon. This character falls within the Arabic Extended-B block, which was added to support additional letters for languages with non-standard Arabic orthographies. It allows for more precise transcription of regional pronunciations, where the inverted small V often denotes a voiced or implosive variant of the sound typically associated with noon.
