Remember
Character ↫
Unicode U+21AB
Hex entity ↫
Decimal ↫
Named entity ↫
CSS escape \21AB
Not the same ↬ (↬) · ↩ (↩)
All of these produce the same glyph: ↫ (when the font supports U+21AB). Prefer ↫ in HTML source for clarity; use hex/decimal when generating entities, and CSS \21AB only in content.

How It Works
1. Hex:U+21AB → ↫ in HTML. The browser turns it into ↫.
2. Decimal: same code point as 8619 → ↫. Same result as hex.
3. Named:↫ is the HTML5 name for this character.
4. CSS: use \21AB in content (not an HTML entity). #point::after appends that ↫ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Left Arrow Loop.
Direction
Left vs right loop
↫ is ↫. The rightwards form is ↬ (↬, U+21AC).
Look-alikes
Not the hook ↩
↩ (U+21A9) is a leftwards arrow with a hook — no loop. Different shape and code point.
A11y
Label the action
Pair ↫ with words like “Undo” or “Loop back”, or use aria-label.
CSS vs HTML
Do not mix escapes
\21AB belongs in CSS. ↫ / ↫ / ↫ belong in HTML.
Fonts
Arrows coverage
Most modern UI fonts include U+21AB. If a glyph is missing, try Segoe UI Symbol or Noto Sans Symbols.
Semicolon
End references
Always finish with ; — write ↫, not &larrlp.
