U+813B "脻" CJK Unified Ideograph-# Unicode Character

U+813B "脻" CJK Unified Ideograph-# is a Chinese character (hanzi) that historically denotes a secondary path or a small, narrow road, often used in classical texts to refer to a less traveled or minor passageway. It is part of the CJK (Chinese, Japanese, Korean) unified ideograph block, encoded for digital representation of East Asian script. The character appears in ancient Chinese literature, notably in philosophical works, where it can be interpreted figuratively to suggest a side route or an alternative means of proceeding. However, in modern usage, U+813B is rare and largely obsolete, primarily encountered in scholarly contexts or specialized dictionaries rather than in everyday writing or digital communication.
