U+18172 "𘅲" Tangut Ideograph-# Unicode Character

U+18172 "𘅲" Tangut Ideograph-# is a specific logogram from the Tangut script, a writing system used to record the extinct Tangut language of the Western Xia dynasty (11th–13th centuries). This particular ideograph, assigned to a block of characters designated for Tangut script in the Unicode Standard, remains largely unglossed with a known modern meaning, often labeled with a placeholder "#" in standard character databases because its exact semantic value has not yet been definitively deciphered or attested. It represents one of the thousands of Tangut characters preserved primarily in historical Buddhist texts and administrative documents, and its inclusion in Unicode allows for digital preservation and scholarly research into this complex, logographic script.
