What Is the Up Paired Arrows Entity?

Up Paired Arrows (⇈) is the Arrows-block character at Unicode U+21C8 (UPWARDS PAIRED ARROWS). HTML5 names it &uuarr; and &upuparrows;. Use it for scroll-up cues and math that needs two upward arrows as one glyph.

Remember

Character     ⇈
Unicode       U+21C8
Named entity  &uuarr; · &upuparrows;

Decimal       &#8648;
CSS escape    \21C8
Not the same  &uarr; (↑) · &uArr; (⇑) · &uHar; (⥣)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: ⇈. Prefer &uuarr; or ⇈ in HTML markup. For a single up arrow see ↑; for paired up harpoons see &uHar;.

Five ways to display ⇈ in HTML and CSS.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Up Paired Arrows (⇈)</title>
  <style>
    #point::after {
      content: "\21C8";
    }
  </style>
</head>
<body>
  <p>Built with Named: &uuarr;</p>
  <p>Built with Hex: &#x21C8;</p>
  <p>Built with Decimal: &#8648;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: ⇈</p>
  <p>Scroll up &uuarr;</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: &uuarr; (or &upuparrows;) is the HTML5 name for U+21C8 → ⇈ (case-sensitive).

2. Hex: ⇈ inserts the same code point. Same visual as named.

3. Decimal: same code point as 8648 → ⇈.

4. CSS: use \21C8 in content (not an HTML entity). #point::after appends ⇈.

5. Typed: paste ⇈ in a UTF-8 document, or write Scroll up &uuarr;.

Pitfalls & Tips

Common mistakes when working with Up Paired Arrows.

Named

Prefer `&uuarr;`

Both &uuarr; and &upuparrows; work. Names are case-sensitive — do not confuse with &uArr; (double up arrow).

Look-alikes

⇈ ≠ ↑ ≠ ⇑ ≠ ⥣

Paired arrows are &uuarr;. Single is ↑. Double (thick) is &uArr;. Harpoons are &uHar;. Match the glyph to your meaning.

A11y

Add context

A lone ⇈ may be unclear. Pair it with wording such as “scroll up” or an accessible name on the control.

Fonts

Glyph coverage

Most system fonts include Arrows-block glyphs. Still test on mobile if the symbol is critical UI chrome.

CSS vs HTML

Do not mix escapes

\21C8 belongs in CSS. &uuarr; / ⇈ / ⇈ belong in HTML.

Semicolon

End references

Always finish with ; — write &uuarr;, not &uuarr.
