Definition

What Is Ww Stack?

Ww Stack (ʬ) is Unicode U+02AC (LATIN LETTER BILABIAL PERCUSSIVE) in IPA Extensions. It is a phonetic letter for a rare bilabial percussive speech sound. HTML5 has no named entity.

Remember

Character     ʬ
Unicode       U+02AC
Hex entity    &#x02AC;
Decimal       &#684;
CSS escape    \02AC
Named entity  (none)
Official name LATIN LETTER BILABIAL PERCUSSIVE
Not the same  ʭ (bidental)

Prefer ʬ or ʬ in HTML markup. You can also type ʬ in UTF-8. There is no named entity. Related: bidental percussive (U+02AD).

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Direct character	`ʬ`	HTML text (UTF-8)
Hex entity	`ʬ`	HTML markup (preferred)
Decimal entity	`ʬ`	HTML markup
CSS escape	`\02AC`	Stylesheet `content`
Named entity	—	Not defined in HTML5

When to Use Which

Situation	Use
Bilabial percussive in IPA	`ʬ` or type `ʬ`

Hex + Decimal + CSS + Typed

Four ways to produce ʬ in a single document (no named entity).

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Ww Stack (ʬ)</title>
  <style>
    #point::after {
      content: "\02AC";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x02AC;</p>
  <p>Using HTML Code: &#684;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Typed directly: ʬ</p>
  <p>Gloss: bilabial percussive</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+02AC → ʬ in HTML. The browser turns it into ʬ.

2. Decimal: same code point as 684 → ʬ. Same result as hex.

3. CSS: use \02AC in content (not an HTML entity). #point::after appends that ʬ after the paragraph text.

4. Typed / gloss: paste ʬ in UTF-8, and add a short gloss so non-specialists understand the IPA letter.

5. No named entity: HTML5 does not define a name for U+02AC — use numeric references or type the character.

Pitfalls & Tips

Common mistakes when working with U+02AC.

Named?

No named entity

HTML5 does not define a named entity for U+02AC. Use ʬ or ʬ.

vs ʭ

Not bidental percussive

ʭ (U+02AD) is bidental. ʬ is bilabial. Related IPA letters — different code points.

Gloss

Explain the sound

Most readers will not recognize ʬ. Add a short gloss like “bilabial percussive.”

Do not rely on the glyph alone

Screen readers may skip or misname IPA letters. Provide visible gloss text next to the symbol.

CSS vs HTML

Do not mix escapes

\02AC belongs in CSS strings. ʬ / ʬ belong in HTML.

Fonts

Need IPA coverage

Some UI fonts omit IPA Extensions. Prefer fonts with solid phonetic coverage (for example Doulos SIL or Charis SIL).

Compatibility

Browser Support

Ww Stack / bilabial percussive (U+02AC) and its entity forms (ʬ, ʬ, CSS \\02AC) are supported in all mainstream browsers. Visible glyphs depend on IPA Extensions font coverage.

✓ Universal support

Ww Stack (ʬ)

Encode with hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

100% Browser coverage

U+02AC / entities Full support

Bottom line: Prefer ʬ or ʬ in HTML. Use \\02AC only inside CSS content. There is no named entity. Always gloss the IPA letter for beginners.

Remember

Key Takeaways

Unicode: this letter is U+02AC (decimal 684) — LATIN LETTER BILABIAL PERCUSSIVE.
HTML: use ʬ or ʬ — no named entity; typing ʬ also works.
CSS: use \02AC inside content for generated text.
Watch out: ʬ ≠ ʭ; always gloss for non-specialists.

One line: U+02AC → ʬ / ʬ / CSS \02AC.
