U+1ED4 "Ổ" Latin Capital Letter O with Circumflex and Hook Above Unicode Character

U+1ED4 "Ổ" Latin Capital Letter O with Circumflex and Hook Above is a specialized letter used primarily in the Vietnamese alphabet to represent a specific tonal variant of the vowel “O,” where the circumflex indicates a narrow, closed pronunciation and the hook above (called a dấu hỏi) marks the hỏi tone, characterized by a mid-low, dipping, and then rising pitch. It appears in Vietnamese words like “ổ” meaning “nest” or “đổ” meaning “to pour,” and is encoded in Unicode to support accurate digital representation of the Vietnamese language, ensuring that this distinct character can be properly rendered, stored, and exchanged across computing systems and text platforms.
