Definition

What Is the Uppercase B Latin Entity?

Uppercase B Latin (ʙ) is the Unicode character at U+0299 (LATIN LETTER SMALL CAPITAL B) in IPA Extensions. It is a small capital B used in phonetic notation, IPA transcriptions, and linguistic text — not the same as ordinary capital B.

Remember

Unicode       U+0299
Hex entity    &#x0299;
Decimal       &#665;
CSS escape    \0299
Named entity  (none)

All of these produce the same glyph: ʙ. Compare with Uppercase B (U+0042) and Uppercase B Hook (U+0181).

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase B Latin</title>
  <style>
    #point::after {
      content: "\0299";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x0299;</p>
  <p>Using HTML Code: &#665;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Typed directly: &#x0299;</p>
  <p>Compare: B &#x0299; b</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+0299 → ʙ in HTML. The browser turns it into the glyph.

2. Decimal: same code point as 665 → ʙ. Same result as hex.

3. CSS: use \0299 in content (not an HTML entity). #point::after appends that glyph after the paragraph text.

4. Compare: B ʙ b shows how the small capital sits between full capital and lowercase.

Pitfalls & Tips

Common mistakes when working with this character.

Named?

No named entity

HTML5 does not define a named entity for U+0299. Use numeric forms.

Look-alikes

Not the same as capital B

U+0299 is a small capital for IPA. U+0042 is ordinary B. U+0181 is B with hook. Do not swap them.

Fonts

Use IPA-capable fonts

Not every font covers IPA Extensions. Prefer fonts that include U+0250–U+02AF for reliable glyphs.

CSS vs HTML

Do not mix escapes

\0299 belongs in CSS. ʙ / ʙ belong in HTML.

A11y

Explain phonetic symbols

Screen readers may not name IPA symbols clearly. Add plain-language context near transcriptions.

Semicolon

End references

Always finish with ; — write ʙ, not &#665.
