U+18640 "𘙀" Tangut Ideograph-# Unicode Character
Unicode Version 17.0
𘙀
U+18640 "𘙀" Tangut Ideograph-# is a specific character from the Tangut script, an ancient logographic writing system used to record the extinct Tangut language of the Western Xia dynasty in medieval China. This character, like others in its block, represents a word or morpheme rather than a sound, and its precise meaning remains largely undeciphered, as many Tangut ideographs have yet to be fully understood by scholars. It was encoded in Unicode as part of a broader effort to preserve and digitally represent historical scripts for linguistic research and digital typography.
