U+5C21 "尡" CJK Unified Ideograph-# Unicode Character

U+5C21 "尡" CJK Unified Ideograph-# is a rare Chinese character that has historically been used as a variant of the glyph meaning "to shine" or "bright," primarily associated with the sun's radiance. Its structure combines the "small" (小) radical with the phonetic component "昆" (kūn), which can also suggest meanings related to "older brother" or "swarm," though the overall character is extremely uncommon in modern Chinese texts. This ideograph is classified under the Kangxi radical 42 (小) and appears in classical dictionaries such as the Kangxi Zidian, where it is noted for its usage in ancient script as a variant form of the character 晄 or 晃. Despite its obscurity, it remains encoded in the CJK Unified Ideographs block to preserve historical linguistic records for specialized scholarly and typographic purposes.
