What Is the Left Harpoon Barb Up Entity?

Left Harpoon Barb Up (↼) is the Arrows character at Unicode U+21BC (LEFTWARDS HARPOON WITH BARB UPWARDS). It is a leftwards harpoon whose barb points up — common in math and chemistry notation.

Remember
Character     ↼
Unicode       U+21BC
Hex entity    ↼
Decimal       ↼
Named entity  ↼  (alias ↼)
CSS escape    \21BC
Not the same  ↽ (↽) · ← (←)

All of these produce the same glyph: ↼. Prefer ↼ when you want an explicit entity.

All four ways to produce ↼ in a single document.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Left Harpoon Barb Up (↼) in HTML</title>
  <style>
    #point::after {
      content: "\21BC";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x21BC;</p>
  <p>Using HTML Code: &#8636;</p>
  <p>Using Named Entity: &lharu;</p>
  <p id="point">Using CSS Entity: </p>
  <p><code>A &lharu; B</code></p>
</body>
</html>
Try It Yourself

How It Works

1. Hex: U+21BC → &#x21BC; in HTML. The browser turns it into ↼.

2. Decimal: same code point as 8636 → &#8636;. Same result as hex.

3. Named: &lharu; is the HTML5 name (alias &leftharpoonup;).

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

Pitfalls & Tips

Common mistakes when working with Left Harpoon Barb Up.

Look-alikes

↼ ≠ ↽ ≠ ←

Barb up (&lharu;), barb down (&lhard;), and plain left (&larr;) are different characters.

Alias

&leftharpoonup; works too

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

Name

Use &lharu; exactly

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

CSS vs HTML

Do not mix escapes

\21BC belongs in CSS. &lharu; / &#x21BC; / &#8636; 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 &lharu;, not &lharu.
