U+7AC7 "竇" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
竇
U+7AC7 "竇" CJK Unified Ideograph-# is a traditional Chinese character primarily meaning "hole," "cave," or "aperture," and it also functions as a surname. Historically, it conveys the sense of a passage or opening, often used in Classical Chinese literature to denote a narrow or deep concavity. In modern usage, while less common in daily writing, it appears in formal texts and surnames, and its simplified counterpart is "窦." The character is composed of the radical for "cave" (穴) beneath the component representing "sell" or "trade" (賣), though the overall pictophonetic structure suggests a dwelling or recess. Its Unicode inclusion reflects the encoding of traditional East Asian characters for digital text representation.
