What ⬨ means
⬨ is the white medium lozenge. 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+2B28. In HTML that is ⬨, and in CSS \2B28.
