U+00C5 "Å" Latin Capital Letter A with Ring Above Unicode Character

U+00C5 "Å" Latin Capital Letter A with Ring Above is a distinct letter in several Scandinavian alphabets, including Swedish, Danish, and Norwegian, where it represents a vowel sound distinct from a plain "A". Historically, the small ring above the letter originated as a diacritic representing a reduced "o" sound, and in these languages, it is treated as a separate letter in the alphabet, often placed at the end. In English and other contexts, it is sometimes used in loanwords, such as the Swedish city name "Åmål" or the symbol for the angstrom unit of length in physics, where it denotes a measure of atomic-scale distances.
