U+18890 "𘢐" Tangut Component-145 Unicode Character

U+18890 "𘢐" Tangut Component-145 is a glyph element from the Tangut script, which was used to write the extinct Tangut language of the Western Xia dynasty (1038–1227). This component appears in the Unicode Standard's Tangut Components block, a collection of 755 abstract or partial radicals and sub-characters that were derived from the physical decomposition of complex Tangut logographs to aid in their digital encoding and linguistic analysis. Specifically, U+18890 represents the 145th such component, a structural piece that would typically form a part of a larger, fully formed Tangut character, but it has no independent meaning or pronunciation on its own. Its inclusion in Unicode allows scholars and software to accurately model, index, and search the thousands of historical Tangut characters by their constituent building blocks.
