Tangut character 18347

It means “to gallop” in Tangut.

A Tangut–Chinese dictionary by Li Fanwen gives this exact character the verb “to gallop”: it names the action, not the animal. The Tangut script was created at the court of the Western Xia state under its first emperor, Li Yuanhao, around 1036, as part of state-building and to support a Buddhist canon—a collection of sacred texts. Tangut books also carried Chinese works translated into the new script, alongside official, private, and religious writing. After the state fell to the Mongols in 1227, Tangut writing continued under the Yuan and Ming dynasties, but had fallen out of use by the end of the Ming dynasty. Scholars rediscovered it in the late 19th century.

Is 𘍇 Chinese or Tangut?

It is Tangut, not a Chinese character. Tangut characters can look Chinese because the script borrowed visual and compositional principles from Chinese writing, but it remained a distinct system for a different language. Earlier, the Khitan, a neighboring medieval people, had also created writing systems for their language. That connects writing traditions; it does not establish that this exact glyph comes from a Chinese or Khitan character.

Why might 𘍇 show as a box?

A font without Tangut support is the likely cause. Unicode notes that historical sources contain variant Tangut glyph shapes; variants that do not distinguish meaning may share one encoded character, so supported fonts can still draw it differently. Use a font with Tangut coverage, and do not substitute a similar-looking Chinese character.
