What You'll Learn

How to display the Bidental Percussive letter (ʭ) in HTML and CSS. This character is U+02AD in the IPA Extensions block (U+0250–U+02AF). In the International Phonetic Alphabet it marks a bidental percussive consonant: a percussive sound made with upper and lower teeth. It appears in narrow phonetic transcription, linguistic corpora, and clinical speech notes.

There is no named HTML entity for U+02AD. Use ʭ or ʭ in markup, or \02AD in stylesheet content. Stack IPA-capable fonts (for example Gentium Plus, Charis SIL, Doulos SIL, or Noto Sans IPA) and set lang appropriately so ʭ matches the rest of your transcription.

Complete HTML Example

This example shows Bidental Percussive using hexadecimal and decimal character references, plus a CSS content escape on a pseudo-element:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\02AD";
  }
 </style>
</head>
<body>
<p>Bidental Percussive using Hexa Decimal: &#x02AD;</p>
<p>Bidental Percussive using HTML Code: &#685;</p>
<p id="point">Bidental Percussive using CSS Entity: </p>
</body>
</html>

🧠 How It Works

1

Hexadecimal Code

&#x02AD; references code point U+02AD using hex digits 02AD after the #x prefix.

HTML markup
2

Decimal HTML Code

&#685; is the decimal equivalent (685) for the same Bidental Percussive letter.

HTML markup
3

CSS Entity

\02AD is the CSS escape for U+02AD, used in the content property of ::before or ::after.

CSS stylesheet
=

Same visual result

Hex, decimal, and CSS escapes all produce ʭ. There is no named HTML entity for U+02AD.

Use Cases

The Bidental Percussive letter (ʭ) is commonly used for:

📚 IPA strings

Narrow and comparative transcriptions where percussive articulation must be spelled out.

🎓 Teaching phonetics

Slides and handouts on manner of articulation and rare IPA letters.

📄 Linguistic corpora

Web-facing concordance lines or dictionary entries stored as UTF-8 HTML.

🏥 Speech pathology

Session notes describing atypical percussive articulations in disordered speech.

🌍 Dialect documentation

Field reports when a language’s inventory includes this rare letter (verify with primary sources).

🗃 Font QA

Rendering checks for SIL or custom IPA webfonts before publication.

♿ Accessibility

Expose “bidental percussive” or IPA X-SAMPA alongside the glyph when readers may not know ʭ by sight.

💡 Best Practices

Do

  • Load Gentium Plus, Charis SIL, Doulos SIL, or Noto Sans/Serif with IPA coverage via @font-face or Google Fonts where available
  • Use UTF-8 and numeric references interchangeably; both are fine for static and CMS content
  • Document your transcription standard (IPA chart revision, language-specific conventions)
  • Use \02AD only inside CSS content, not inside HTML text nodes
  • Pair rare glyphs with a spoken or written gloss for learners

Don’t

  • Confuse bidental percussive ʭ with unrelated Latin letters or combining marks
  • Assume every visitor’s default sans font draws ʭ with IPA-correct proportions
  • Label dialect sounds without citations from linguistics references
  • Ship standalone ʭ icons in UI with no textual equivalent for assistive tech
  • Mix legacy Windows-1252 pages with raw ʭ without declaring charset UTF-8

Key Takeaways

1

Two numeric references render the same glyph

&#x02AD; &#685;
2

In CSS content, use the escape

\02AD
3

U+02AD is IPA Extensions; no &name; entity exists

4

IPA fonts are part of the solution, not just the HTML reference

5

Add glosses or X-SAMPA when the audience is not phonetics-trained

❓ Frequently Asked Questions

Use &#x02AD; (hex), &#685; (decimal), or \02AD in CSS content. There is no named entity; all valid methods render ʭ.
U+02AD (hex 02AD, decimal 685). IPA Extensions block; Unicode name LATIN LETTER BIDENTAL PERCUSSIVE.
Whenever your IPA transcription or clinical note requires this exact letter and you are publishing UTF-8 HTML instead of images or PDF only.
Numeric references belong in HTML. The \02AD escape belongs in stylesheets (for example on pseudo-elements). Do not paste CSS escapes into HTML text nodes.
No. Use &#x02AD;, &#685;, or \02AD in CSS depending on whether you are authoring markup or styles.
