Not the same ⟵ (⟵) · ⇐ (⇐)
Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⟸. Prefer ⟸ in HTML source for clarity. Case is significant: ⟸ ≠ ⟵.

How It Works
1. Named:⟸ (aliases ⟸, ⟸) is the clearest HTML form and renders ⟸.
2. Hex:U+27F8 → ⟸ in HTML. Same result as the named entity.
3. Decimal: same code point as 10232 → ⟸. Same result as hex.
4. CSS: use \27F8 in content (not an HTML entity). #point::after appends that ⟸ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Long Left Double Arrow.
Case
⟸ ≠ ⟵
Capital A selects the double arrow (U+27F8). Lowercase ⟵ is the single long arrow (U+27F5).
Length
⟸ ≠ ⇐
The short left double arrow is ⇐ (U+21D0). Use U+27F8 only when you need the long form.
Aliases
Three named forms
⟸, ⟸, and ⟸ all map to U+27F8. Prefer one style consistently.
CSS vs HTML
Do not mix escapes
\27F8 belongs in CSS. ⟸ / ⟸ / ⟸ belong in HTML.

Add nearby words
Pair the glyph with labels (for example Q ⟸ P) or use aria-label when it stands alone.
Semicolon
End references
Always finish with ; — write ⟸, not &xlArr.
