U+9FEF "鿯" CJK Unified Ideograph-# Unicode Character

U+9FEF "鿯" CJK Unified Ideograph-# is a rare and relatively recently encoded Chinese character, included in Unicode version 11.0 in 2018 as part of the CJK Unified Ideographs block, which contains traditional and simplified characters from Chinese, Japanese, and Korean. This particular ideograph is known to be a variant of the character used in old, obscure, or dialectal vocabulary, though its precise meaning and usage are not well documented in common Chinese texts. Its encoding was driven by scholarly efforts to digitize ancient manuscripts and ensure that all characters, even those with extremely limited use, have a digital representation. As a result, U+9FEF represents the ongoing effort to preserve linguistic diversity within digital standards, even for characters that may only appear in a handful of historical documents.
