U+18666 "𘙦" Tangut Ideograph-# Unicode Character

U+18666 "𘙦" 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) in northwestern China. This ideograph corresponds to a particular word or morpheme within the Tangut lexicon, though its exact meaning is often identified only by its numbered position in the Unicode standard due to the incomplete decipherment of many Tangut characters. As part of the Tangut block in Unicode, it contributes to the digital preservation of this historically significant script, enabling scholars and linguists to study and encode the vast corpus of Tangut texts that survive primarily in manuscripts and inscriptions.
