Unicode Block - CJK Radicals Supplement
CJK Radicals Supplement is a collection of alternative and simplified forms of Chinese character components, often used in dictionaries and historical texts, that are distinct from the standard Kangxi radicals. These glyphs serve as reference markers for finding characters in radical-stroke index systems, particularly for traditional and variant character shapes that do not appear in the main radical set. The supplement includes both single-stroke and multi-stroke forms, covering variations derived from seal script and other archaic scripts, as well as simplified versions used in modern Chinese, Japanese, and Korean typography. Its purpose is to provide a unified encoding for these non-standard radicals, ensuring consistent identification and sorting without overlapping with the regular radical block.
