U+1EDE "Ở" Latin Capital Letter O with Horn and Hook Above Unicode Character
Unicode Version 17.0
Ở
U+1EDE "Ở" Latin Capital Letter O with Horn and Hook Above is a specialized letter used in the Vietnamese alphabet to represent the distinct vowel sound that begins with an O and is modified by a horn diacritic, combined with a hook above to indicate the low-falling, breathy tone often referred to as the "hỏi" tone. This character is essential for accurately writing Vietnamese words like "ở" meaning "at" or "to be located," and it is formed by adding the horn, which attaches to the right side of the O, and the hook above, which sits above the letter to denote tonal nuance. Its inclusion in the Unicode standard ensures that digital text can properly represent this specific Vietnamese phoneme across different platforms and software.
