U+02DA "˚" Ring Above Unicode Character
Unicode Version 17.0
˚
U+02DA "˚" Ring Above is a diacritical mark that appears as a small circle positioned above a letter, used in various writing systems to modify its pronunciation. It is most commonly recognized in Danish, Norwegian, Swedish, and Finnish where it forms the letter "å," representing a distinct vowel sound, but it also appears in other languages such as Czech for a long vowel or in the International Phonetic Alphabet to indicate a specific phonetic feature. Its design is conceptually derived from a superscript version of the letter "o" and serves to distinguish words or sounds that would otherwise be ambiguous.
