U+0555 "Օ" Armenian Capital Letter Oh Unicode Character

U+0555 "Օ" Armenian Capital Letter Oh is a distinct letter in the Armenian alphabet, primarily used in the classical or reformed orthography to represent the open back rounded vowel sound /ɔ/, similar to the "o" in English "more." It is the 37th letter of the alphabet and is typically employed in transliterations of foreign words or in specific Armenian dialects, as its usage has diminished in modern standard Eastern Armenian, where the letter "Ո" often takes on a similar phonetic role. The uppercase form features a unique, rounded shape with a slight loop, and it corresponds to the lowercase "օ" (U+0585).
