Definition

What Is the Right Harpoon Barb Up Entity?

Right Harpoon Barb Up (⇀) is the Arrows character at Unicode U+21C0 (RIGHTWARDS HARPOON WITH BARB UPWARDS). It is a rightwards harpoon whose barb points up — common in math and chemistry notation.

Remember

Character     ⇀
Unicode       U+21C0
Hex entity    &#x21C0;
Decimal       &#8640;
Named entity  &rharu;  (alias &rightharpoonup;)
CSS escape    \21C0
Not the same  &rhard; (⇁) · &rarr; (→)

All of these produce the same glyph: ⇀. Prefer &rharu; when you want an explicit entity.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Right Harpoon Barb Up (⇀) in HTML</title>
  <style>
    #point::after {
      content: "\21C0";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x21C0;</p>
  <p>Using HTML Code: &#8640;</p>
  <p>Using Named Entity: &rharu;</p>
  <p id="point">Using CSS Entity: </p>
  <p><code>A &rharu; B</code></p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+21C0 → ⇀ in HTML. The browser turns it into ⇀.

2. Decimal: same code point as 8640 → ⇀. Same result as hex.

3. Named: &rharu; is the HTML5 name (alias &rightharpoonup;).

4. CSS: use \21C0 in content (not an HTML entity). #point::after appends that ⇀ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Right Harpoon Barb Up.

Look-alikes

⇀ ≠ ⇁ ≠ →

Barb up (&rharu;), barb down (&rhard;), and plain right (→) are different characters.

Alias

`&rightharpoonup;` works too

It is an HTML5 alias for the same character as &rharu;.

Name

Use `&rharu;` exactly

Guessing names will not work. Stick to &rharu; or numeric forms.

CSS vs HTML

Do not mix escapes

\21C0 belongs in CSS. &rharu; / ⇀ / ⇀ belong in HTML.

A11y

Add nearby words

Pair the glyph with equation text or use aria-label when it stands alone.

Semicolon

End references

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