U+54CE "哎" CJK Unified Ideograph-# is a Chinese character that functions primarily as an interjection, commonly used in spoken Mandarin to express a range of emotions such as surprise, regret, disapproval, or to call attention. It often appears in phrases like "哎呀" (āiyā) to convey mild shock or dismay, or "哎哟" (āiyō) to indicate sudden pain or astonishment. In written form, it can also serve as a filler or prompt in narrative dialogues, similar to "hey" or "oh" in English. As part of the CJK (Chinese, Japanese, and Korean) unified ideographs block, this character is integral to everyday vernacular expression across multiple East Asian languages.
