All of these produce the same glyph: ⤆. Prefer ⤆ (or ⤆) when you need an entity — there is no named form.

How It Works
1. Hex:U+2906 → ⤆ in HTML. The browser turns it into ⤆.
2. Decimal: same code point as 10502 → ⤆. Same result as hex.
3. CSS: use \2906 in content (not an HTML entity). #point::after appends that ⤆ after the paragraph text.
4. No named entity: HTML5 does not define &…; for this character — stick to numeric forms.
Pitfalls & Tips
Common mistakes when working with Left Double Arrow Bar.
Look-alikes
⤆ ≠ ⇐ ≠ ⇤
Double-from-bar, plain double (⇐), and single-to-bar (⇤) are different points.
Named
No named entity
Guessing names like &Mapsto; will not produce U+2906. Use ⤆.
Fonts
Glyph may be missing
Supplemental Arrows-B coverage varies. Test on your target devices or provide a fallback font.
CSS vs HTML
Do not mix escapes
\2906 belongs in CSS. ⤆ / ⤆ belong in HTML.

Add nearby words
Pair the glyph with text like “Start”, or use aria-label on icon-only controls.
Semicolon
End references
Always finish with ; — write ⤆, not ⤆.
