Tangut Component 202

It is a structural component, not a Tangut word.

Here, “component” means an element recognized within a full Tangut character. Scholars use components to find, describe, and analyze characters in dictionaries and in Ideographic Description Sequences (IDS), short formulas that show a character’s structure. This isolated mark has no independent word meaning.

Created under the first emperor of Western Xia around 1036, Tangut (also called Xixia) was used to write the Tangut language. Its characters may resemble Chinese ideographs, but Tangut is a distinct script. It appears in official, private, and religious texts, including Buddhist works; Buddhist translation also connected it with Tibetan traditions. After Western Xia fell to the Mongols, Tangut continued in Yuan and Ming texts and was obsolete by the end of the Ming dynasty. Scholars rediscovered it in the late 19th century.

Why does 𘣉 show as a square?

A font without Tangut coverage is the usual reason.

If an app’s active font lacks Tangut coverage, it may replace the glyph with an empty box or another missing-character mark. That placeholder is a display failure, not a different Tangut character or reading.
