U+18BD9 "𘯙" Khitan Small Script Character-# Unicode Character

U+18BD9 "𘯙" Khitan Small Script Character-# is a specific logographic or syllabic grapheme from the Khitan Small Script, a writing system used by the Khitan people of the Liao Dynasty in northern China from the 10th to the 12th centuries. This script, which was deciphered only partially in modern times, comprises hundreds of distinct characters that represent morphemes or syllables of the now-extinct Khitan language, and U+18BD9 represents one such unnumbered or placeholder glyph often used in digital encoding to denote an unspecified character within the script’s repertoire. Its inclusion in the Unicode Standard, specifically in the Supplementary Multilingual Plane, allows for the digital preservation and study of this historical writing system, though its exact phonetic or semantic value remains unknown due to the incomplete decipherment of the script.
