What ∹ means
∹ is the excess. Unicode classifies it as a mathematical symbol and files it in the Mathematical Operators 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, U2239. In HTML that is ∹, and in CSS \2239.
Questions people ask
1Why does ∹ 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.
