Khitan small-script character 18BBE

This is a Khitan small-script sign from a system for writing Khitan; the Unicode label doesn't give its meaning. Traditionally dated to the tenth century, its forms drew on Chinese characters and its sound system on Uyghur writing; a 2026 study argues it was systematized later. The oldest securely dated inscription is from 1051. Khitan writing persisted under Jin rule until 1191, and Jurchen script-makers modeled their writing on it.
