What ⦴ means
⦴ is the empty set with left arrow above. Unicode classifies it as a mathematical symbol and files it in the Miscellaneous Mathematical Symbols-B block; this site shelves it under Maths.
Its appearance depends on the font and text styling.
How it is encoded
⦴ is a single code point, U29B4. In HTML that is ⦴, and in CSS \29B4.

Questions people ask
1Why does ⦴ show as a box on some devices?
Not every system ships a font for the Miscellaneous Mathematical Symbols-B block. Where none is installed, the character shows as an empty box; adding a font such as Noto fixes it. The character itself is still correct and copies correctly.
