U+5318 "匘" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
匘
U+5318 "匘" CJK Unified Ideograph-# is a Chinese character classified under the "CJK Unified Ideographs" block, and it is an ancient or less common variant form of the character "脑" (nǎo), which means "brain" in modern Chinese. Historically, this ideograph was used in classical texts and traditional writing, sharing the same semantic meaning related to the encephalon or mental faculties. Its structure combines the radical for a container or enclosure resembling a receptacle with phonetic and semantic components, though in contemporary usage, it is largely obsolete and replaced by the more standard character 脑. As part of the CJK standard, it ensures that historical and regional script variations remain digitally representable.
