What 𘆼 means
𘆼 is the tangut ideograph-181bc. Unicode classifies it as a letter and files it in the Tangut block; this site shelves it under Chinese, Japanese & Korean.
Its appearance depends on the font and text styling.
How it is encoded
𘆼 is a single code point, U+181BC. In HTML that is 𘆼, and in CSS \181BC.

1Why does 𘆼 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
