Anticlockwise top semicircle arrow (↶) is Unicode U+21B6 in the Arrows block. It is a curved arrow that turns anticlockwise (counterclockwise) — often used for undo, rewind, or rotate-left cues. HTML provides the named entity ↶.
Remember
Character ↶
Unicode U+21B6
Hex entity ↶
Decimal ↶
Named entity ↶
CSS escape \21B6
Partner ↷ U+21B7 → ↷
All of these produce the same glyph: ↶. Prefer ↶ in hand-written HTML; type ↶ in UTF-8 when you can; use numeric or CSS forms for generated content.

Typed directly: ↶
How It Works
1. Hex:U+21B6 → ↶ in HTML. The browser turns it into ↶.
2. Decimal: same code point as 8630 → ↶. Same result as hex.
3. Named:↶ is the standard HTML name for U+21B6 — clear in source.
4. CSS: use \21B6 in content (not an HTML entity). #point::after appends that ↶ after the paragraph text.
5. Typed ↶: fine in UTF-8 source. All five lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with the anticlockwise arrow (↶) entity.
Direction
Do not swap with clockwise
↶ is ↶. ↷ is ↷. Match the action you mean.
Circle
Not a full refresh circle
U+21B6 is a top semicircle. For full loops, use open/closed circle arrow entities.
CSS vs HTML
Do not mix escapes
\21B6 belongs in CSS. ↶ / ↶ belong in HTML.
Fonts
Arrow coverage varies
Some UI fonts omit curved Arrows-block glyphs. Prefer fonts with solid arrow coverage.
A11y
Label the action
Pair ↶ with text like “Undo” so meaning does not rely on the glyph alone.
Semicolon
End references
Always finish with ; — write ↶, not &cularr.
