U+30AA "オ" Katakana Letter O Unicode Character

U+30AA "オ" Katakana Letter O is a character used in the Japanese writing system, specifically within the Katakana syllabary, which is primarily employed for foreign loanwords, onomatopoeia, and scientific terms. It represents the sound "o" and is derived from a simplified form of the Chinese character 於. This character is part of the basic 46-character set of modern Katakana and, when combined with a dakuten diacritic to form ヴォ, can also represent the voiced sound "vo" in adapted loanwords. In Unicode, it was encoded in the Katakana block as part of the Unicode 1.1 standard, and it appears identically to the Hiragana counterpart お in terms of pronunciation but differs in visual style and usage context.
