Tangut character for night

A Tangut dictionary glosses it as “night.”

Tangut was a language spoken in Western Xia, a state in what is now northwestern China. Its script was created under the state’s first emperor in 1036 for state-building; a Tangut Buddhist canon (collection of scriptures) was likely a main purpose. Though inspired by Chinese writing, Tangut was distinct and followed earlier scripts of neighboring Khitan people. Tangut writing served Buddhist, translated Chinese, and secular texts. A manuscript fragment from Khara-Khoto (Inner Mongolia) probably dates to the 12th or early 13th century. The script continued under the Yuan and Ming dynasties, then became obsolete.
