U+544D "呍" CJK Unified Ideograph-# Unicode Character

U+544D "呍" CJK Unified Ideograph-# is a rare and obscure Chinese character that primarily functions as a regional or variant form of the more common character 呒 (wú), meaning "without" or "to lack," though it also appears in older texts as a transliteration for sounds in foreign names or Buddhist terms. This ideograph belongs to the CJK Unified Ideographs block and is composed of the radical 口 (mouth) on the left and the phonetic component 云 (cloud) on the right, suggesting a possible connection to speech or sound. Its usage is extremely limited in modern Chinese, often confined to historical documents, classical literature, or specialized linguistic studies, and it may not be recognized in standard dictionaries.
