What ⯃ means
⯃ is the horizontal black octagon. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Miscellaneous Symbols and Arrows block; this site shelves it under Stars & signs.
Its appearance depends on the font and text styling.
How it is encoded
⯃ is a single code point, U+2BC3. In HTML that is ⯃, and in CSS \2BC3.
