Tangut Ideograph-17DE5

It's a Tangut word, glossed in dictionaries with Chinese 校. The standard Tangut–Chinese dictionary compiled by the scholar Li Fanwen indexes this character as L0513 and gives the reconstructed reading du̱. The gloss 校 itself runs from 'to check, collate' to 'school' in Chinese — a specialist cross-reference, not a one-word English translation.

For everyone else the official name is a dead end: 'Tangut Ideograph-17DE5' is a catalogue label generated from the script name and code position, and Unicode's own Tangut documentation warns such names say little. The meaning lives in Tangut sentences — dictionaries and text concordances are the way in.

Why was Tangut script made?

A king commissioned it to help build a state. In 1036 the Western Xia ruler Li Yuanhao ordered a new script for his Tangut empire in what is now northwestern China. It wrote state documents, carried translated Chinese classics and Buddhist scriptures, and asserted imperial equality with neighboring powers — the Khitan empire's own invented script was the political precedent. The visual model was Chinese characters, but Tangut's forms are its own.

Manuscripts from the ruins of Khara-khoto date to the 12th and early 13th centuries, including a Tangut translation of a Chinese work on imperial conduct. After Western Xia fell, the script persisted in Buddhist printing — a Tangut edition appeared in 1247, with more under the Yuan — shrinking from a national script to a vessel of religious memory.
