Tangut Iteration Mark

It means: write the preceding Tangut character again.

That is why it is called a Tangut repetition mark: it replaces a second written occurrence. In a cursive example, 𘟪 means “iron”; 𖿠 after it repeats that character.

Tangut was the writing system of the medieval Western Xia state and was used for religious and literary texts. This mark is written shorthand within that script.

What does 𖿠 mean if someone sends it?

Usually, a reference to Tangut writing.

Without a Tangut text around it, the sender’s intended point is unclear; the mark itself gives no settled chat tone.
