What ⮿ means
⮿ is the circled bold x. 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+2BBF. In HTML that is ⮿, and in CSS \2BBF.
