U+18BB1 "𘮱" Khitan Small Script Character-# Unicode Character

U+18BB1 "𘮱" Khitan Small Script Character-# is a specific glyph from the Khitan Small Script, a historical writing system used to record the extinct Khitan language spoken by the Khitan people during the Liao Dynasty in northern China. This script, deciphered only partially by modern scholars, was composed of hundreds of logographic and phonetic symbols, and this particular character represents one of its unassigned or placeholder number signs, often denoted by the hash mark in its official Unicode name to indicate an unidentified or generic numeric function. Its inclusion in the Unicode Standard since version 13.0 in 2020 preserves a piece of the Khitan cultural heritage, aiding in the digital study and documentation of a once powerful but now largely forgotten civilization.
