U+F9DA "栗" CJK Compatibility Ideograph-# Unicode Character

U+F9DA "栗" CJK Compatibility Ideograph-# is a compatibility ideograph originating from the CJK (Chinese, Japanese, and Korean) block, specifically part of the CJK Compatibility Ideographs range. It represents the character for "chestnut" and is a duplicate or variant of the standard CJK Unified Ideograph U+6817, but is encoded separately to preserve its shape and usage from older character set standards, such as those used in legacy Japanese or Korean text. This character is primarily included for roundtrip conversion compatibility with older encoding systems, and its use in modern text is generally discouraged in favor of the unified version.
