U+51D6 "凖" CJK Unified Ideograph-# Unicode Character

U+51D6 "凖" CJK Unified Ideograph-# is a Chinese character (hanzi) that serves as a variant or traditional form of the character 準, which primarily means "standard," "criterion," "accurate," or "to allow." It is composed of the radical 冫 (ice) atop the components 奭 (meaning prosperity or bright, though here it functions phonetically), and it is used in historical or classical texts, as well as in some Japanese and Korean contexts, where it retains the same core meanings related to precision or permission. In modern simplified Chinese, this character has largely been replaced by the simplified form 准, but it remains in use for calligraphy, traditional writing, and technical documentation within the Unicode standard.
