2. Hex / decimal:↡ and ↡ insert the same code point.

4. Typed: paste ↡ in a UTF-8 document, or pair it with a label like Jump ↡.
Pitfalls & Tips
Common mistakes when working with Down Two Headed Arrow.
Case
Watch ↡ vs ↓ vs ⇓
↡ is ↡ (U+21A1). ↓ is ↓ (U+2193). ⇓ is ⇓ (U+21D3). Entity names are case-sensitive.
⇓
Not the double arrow
⇓ is a double-lined shaft. ↡ has two arrowheads on one shaft.

Matching directions
Use ↟, ↞, and ↠ for up, left, and right two-headed arrows.
CSS vs HTML
Do not mix escapes
\21A1 belongs in CSS strings. ↡ / ↡ belong in HTML.
Fonts
Arrow font coverage
Some fonts omit two-headed arrow glyphs. Prefer a font with solid Arrows-block coverage.

Add accessible text
A lone two-headed arrow can be unclear to screen readers. Pair it with visible text or an aria-label.
Semicolon
End references
Always finish entities with ; — write ↡, not &Darr.
