Tangut Character 18573

It names the action of drilling.

Li Fanwen’s Tangut–Chinese dictionary gives that English gloss. If it arrives alone, ask for the surrounding text before guessing what the sender means.

Is 𘕳 a Chinese character?

No; it writes Tangut, not Chinese.

Western Xia, a medieval kingdom in northwestern China, established Tangut writing around 1036 for government and Buddhist texts. Chinese writing shaped its square design, and nearby Khitan rulers provided an earlier example of a state with its own scripts. Those links connect writing systems, not this glyph to a Chinese or Khitan character.

Tangut writing outlived Western Xia, which fell in 1227; a religious monument dated 1502 records its later use. This word’s dictionary gloss cannot reveal a modern sender’s intent.
