U+9FFF "鿿" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

鿿

U+9FFF "鿿" CJK Unified Ideograph-# is a rare and relatively obscure Chinese character that resides at the very end of the Unicode block's initial range for CJK Unified Ideographs, historically serving as a placeholder or boundary marker before the block was extended. This ideograph is not commonly used in modern Chinese, Japanese, or Korean writing, and its precise meaning is often undefined or unattested in standard dictionaries, making it more of a technical or historical Unicode artifact than a practical linguistic symbol. Its inclusion represents the system's effort to cover every possible glyph from historical and regional character sets, even those without clear contemporary usage, highlighting the vast scope and challenges of encoding East Asian scripts.
