U+18B90 "𘮐" Khitan Small Script Character-# Unicode Character

U+18B90 "𘮐" Khitan Small Script Character-# is a specific logographic sign from the Khitan Small Script, a writing system used from the 10th to the 12th centuries by the Khitan people of the Liao Dynasty in northern China to represent their now extinct language. This character belongs to a syllabary that largely remains undeciphered, with many of its over 370 known glyphs, including U+18B90, lacking a definitive phonetic or semantic meaning. It was officially encoded in the Unicode Standard as part of the Khitan Small Script block in version 13.0, added in 2020 to preserve and enable digital study of this historical script. Researchers continue to analyze such characters through comparative studies with Chinese records and similar scripts, though U+18B90’s exact function within the Khitan language’s grammar or vocabulary is not yet fully understood.
