What ↰ means
↰ is the upwards arrow with tip leftwards. Unicode classifies it as an “other symbol” — Unicode's shelf for signs that are neither maths, money nor punctuation and files it in the Arrows block; this site shelves it under Arrows.
Its appearance depends on the font and text styling.
How it is encoded
↰ is a single code point, U+21B0. In HTML that is ↰, and in CSS \21B0.

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.
