U+81EB "臫" CJK Unified Ideograph-# Unicode Character

U+81EB "臫" CJK Unified Ideograph-# is a rare and archaic Chinese character that appears in historical texts and is included in the CJK (Chinese, Japanese, and Korean) Unified Ideographs block. It is composed of the radical 自 (self, oneself) and the phonetic component 刀 (knife), and its precise meaning is obscure, though it may relate to concepts of self-reflection or self-inflicted action in Classical Chinese. Due to its infrequency in modern usage, it is primarily of interest to scholars of historical linguistics, paleography, or those working with ancient manuscript digitization.
