U+815B "腛" CJK Unified Ideograph-# Unicode Character

U+815B "腛" CJK Unified Ideograph-# is a rarely used Chinese character classified under the radical for flesh or meat (⺼), typically indicating a part of the body or a bodily substance. Its precise meaning is obscure in modern standard Chinese, but historical dictionaries suggest it may refer to a form of fat or the fat of an animal, particularly around the abdomen or internal organs. This character appears in ancient texts and specialized lexicons, such as the Kangxi Dictionary, where it is defined with limited usage, and it is not commonly encountered in contemporary writing or daily language, making it a niche component of the CJK (Chinese, Japanese, Korean) unified ideograph set.
