Tangut character 170A1

In Tangut, 𗂡 means “to clean” or “to tidy.” Alone in a message, it reads as a reference to Tangut writing, not a standard reaction.

Tangut was the language of Western Xia (Xixia), a state in what is now northwestern China. Its script was created under the state’s first emperor around 1036, stayed in use after the state fell, and became obsolete by the end of the Ming dynasty.

Tangut writing resembles Chinese characters, but the scripts are separate and unrelated. 𗂡 appears in the Tangut reference works Wénhǎi (“Sea of Writing”) and Tóngyīn (“Homophones”), both from the 12th century.
