U+F99F "烈" CJK Compatibility Ideograph-# Unicode Character

U+F99F "烈" CJK Compatibility Ideograph-# is a compatibility ideograph that corresponds to the CJK unified ideograph for "烈" (liè), which means fierce, intense, or ardent in Chinese and Japanese. It is part of the CJK Compatibility Ideographs block, a set of characters originally encoded for compatibility with older or region-specific standards like Korean KS X 1001 or Japanese character sets, allowing round-trip conversion from such legacy encodings. Unlike standard CJK Unified Ideographs, compatibility characters like U+F99F are generally not recommended for ordinary text interchange, as they are duplicates of unified characters and primarily serve to preserve the exact identity of source text from older systems.
