U+78AE "碮" CJK Unified Ideograph-# Unicode Character

U+78AE "碮" CJK Unified Ideograph-# is a Chinese character (hanzi) that typically refers to a type of ancient stone block, footstone, or a base for a pillar, often used in the context of construction or historical architecture, though it is considered a rare or obsolete glyph in modern usage. As a component of the CJK Unified Ideographs block, it represents a logogram from the Chinese writing system, with its meaning and usage primarily preserved in classical texts or specialized historical references rather than contemporary language. Its structure combines the radical for "stone" (石) with a phonetic component, following the standard pattern for forming ideographic characters in the CJK repertoire.
