U+17D90 "𗶐" Tangut Ideograph-# Unicode Character

U+17D90 "𗶐" Tangut Ideograph-# is a specific glyph from the Tangut script, a logographic writing system used to record the extinct Tangut language of the Xixia Empire (11th–13th centuries). This particular character belongs to the Tangut ideographs block in Unicode, which encodes over 6,000 known Tangut characters that were primarily documented in the 1994 book *Homophones* and other ancient manuscripts. The character's exact meaning and phonetic value are typically identified by its index number within the standard Tangut character set, as many of these ideographs have not yet been fully deciphered or linked to specific Chinese or English glosses in digital databases, though ongoing research continues to reconstruct their usage in historical texts.
