U+553F "唿" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
唿
U+553F "唿" CJK Unified Ideograph-# is a Chinese character that primarily functions as an onomatopoeic or descriptive element in Mandarin, often conveying a sound of urgency or a short, sharp exhalation, such as a whistle or a gasp. It is composed of the radical "口" (mouth) on the left, indicating its relation to speech or sound, and the phonetic component "忽" on the right, which contributes to its pronunciation as "hū". While less common in everyday modern writing, it appears in classical texts, regional dialects, or compound words like "唿哨" (to whistle), and it is standardized in the Unicode system for digital representation of Chinese and other East Asian scripts.
