U+5D7C "嵼" CJK Unified Ideograph-# Unicode Character

U+5D7C "嵼" CJK Unified Ideograph-# is a Chinese ideograph (Han character) used in historical and classical texts, primarily representing the concept of a steep, rugged, or precipitous mountain. This character is composed of the "mountain" radical (山) on the left, indicating its relation to terrain, and a phonetic component on the right that contributes to its pronunciation, which is reconstructed as approximately "chan" or "shan" in Middle Chinese. It appears in ancient dictionaries such as the Shuowen Jiezi and is occasionally encountered in literary works describing treacherous landscapes. While rare in modern Mandarin usage, the character remains part of the CJK (Chinese, Japanese, Korean) unified ideograph block for compatibility with historical documents and specialized terminology.
