U+F984 "濾" CJK Compatibility Ideograph-# Unicode Character

U+F984 "濾" CJK Compatibility Ideograph-# is a compatibility ideograph used primarily in East Asian text processing systems, specifically within the context of Japanese, Chinese, and Korean character sets. It represents a variant or duplicate form of the standard CJK Unified Ideograph U+8FBC (屮), which corresponds to the kanji meaning "used" or "secondhand." This character was included in the Unicode standard to preserve round-trip compatibility with older legacy character encodings, such as those found in certain Japanese industrial standards, where it may have appeared as a distinct glyph. Despite its existence, it is generally not recommended for new text, as it is a duplicate of a unified ideograph and its primary purpose is to ensure that older documents remain accurately rendered in modern systems.
