What You'll Learn

How to display the Retroflex Click symbol (ǃ) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+01C3 (LATIN LETTER RETROFLEX CLICK) in the Latin Extended-B block (U+0180–U+024F)—used in the International Phonetic Alphabet (IPA) to represent a retroflex click sound in linguistic and phonetic documentation.

Render it with ǃ, ǃ, or CSS escape \01C3. There is no named HTML entity. Do not confuse ǃ with the ASCII exclamation mark (!, U+0021)—they look similar but are different characters.

Use Cases

The Retroflex Click symbol (ǃ) is commonly used in:

💬 IPA notation

International Phonetic Alphabet charts and phonetic transcriptions.

📖 Linguistics

Academic papers, dictionaries, and language documentation projects.

🎓 Language learning

Pronunciation guides and phonetics courses for click languages.

Linguistic corpora and phonetic analysis tools on the web.

📋 Unicode references

♿ Accessibility

Pair ǃ with a text description of the sound; use IPA-friendly fonts.

💡 Best Practices

Do

  • Use &#x01C3; or &#451; for inline IPA retroflex click marks
  • Set <meta charset="utf-8"> for reliable rendering
  • Use a font with IPA coverage (e.g. Doulos SIL, Charis SIL)
  • Use ǃ for the retroflex click—not ASCII !
  • Pick one numeric style per project for consistency

Don’t

  • Substitute ASCII exclamation mark ! for ǃ in phonetic text
  • Use padded Unicode notation like U+001C3—the correct value is U+01C3
  • Use CSS escape \01C3 in HTML text nodes
  • Assume every system font renders Latin Extended-B glyphs
  • Confuse retroflex click ǃ with alveolar click ǂ
