U+1DFF "᷿" Combining Right Arrowhead and down Arrowhead Below Unicode Character

U+1DFF "᷿" Combining Right Arrowhead and down Arrowhead Below is a diacritical mark used in a small number of historical or specialized linguistic transcriptions to indicate a specific phonetic modification, such as a particular gliding or contouring of a sound. It combines a rightward-pointing arrowhead with a downward-pointing arrowhead, and is placed beneath a base character to modify its pronunciation, often in scholarly contexts like the representation of African or Asian tones. This character is part of the Combining Diacritical Marks Extended block, and because it has very limited practical use and requires advanced font support, it is rarely encountered outside of highly specialized digital text or academic notation systems.
