U+18664 "𘙤" Tangut Ideograph-# Unicode Character

U+18664 "𘙤" Tangut Ideograph-# is a specific character from the Tangut script, an ancient writing system used for the extinct Tangut language of the Western Xia dynasty (1038–1227). This ideograph represents a distinct logographic symbol within the vast Tangut repertoire, which numbers over 6,000 characters and was deciphered primarily through Chinese-Tangut bilingual texts. The exact meaning of this character, like many Tangut ideographs, remains uncertain or poorly understood due to the language's limited surviving corpus and the complex, highly stylized nature of its script. U+18664 was assigned in the Tangut block of Unicode Standard version 9.0, released in 2016, as part of ongoing efforts to digitally preserve and study this historical writing system.
