U+18B64 "ð˜¤" Khitan Small Script Character-# Unicode Character
U+18B64 "ð˜¤" Khitan Small Script Character-# is a specific glyph belonging to the Khitan Small Script, a historical writing system used by the Khitan people of the Liao dynasty in northern China (907-1125 CE) to write the now-extinct Khitan language. This character is part of a large block of over 470 symbols that were logographic and syllabic in nature, often representing morphemes or syllables rather than individual phonetic sounds, similar to how Chinese characters function. Deciphering this script has been a significant scholarly challenge, with U+18B64 representing one of the many placeholders in the Unicode Standard that awaits a definitive linguistic meaning, typically labeled with a generic hash symbol until its specific historical usage can be identified through ongoing research and comparative analysis with bilingual inscriptions.
