What ⦣ means
⦣ is the reversed angle. 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, U+29A3. In HTML that is ⦣, and in CSS \29A3.
