Direct Character

CSS Entity
\279 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result

Use Cases
The lowercase r reverse (ɹ) is commonly used in:
The standard IPA symbol for the alveolar approximant in English, Irish, and many other languages. Essential for accurate phonetic notation.
Dictionary entries, language-learning apps, and ESL materials showing how words like “red” (/ɹɛd/) are pronounced.
When a font or design includes this IPA character for linguistic or decorative use. Use the entity to output it in HTML or CSS.
When building HTML from phonetic databases or linguistic APIs, using ɹ or ɹ guarantees correct output.
Linguistics papers, phonology textbooks, and speech-science documentation referencing the alveolar approximant symbol.
Using the correct character (U+0279) ensures assistive technologies and screen readers handle phonetic content correctly.
Using \279 in the CSS content property to insert ɹ via pseudo-elements.
💡 Best Practices
Do
- Serve pages as UTF-8; you can type ɹ directly in UTF-8 source
- Use ɹ in IPA phonetic transcription instead of plain
r - Use numeric references (
ɹorɹ) when escaping is required - Use
\279in CSScontentwhen generating the symbol via pseudo-elements - Use fonts that support IPA Extensions (e.g. Doulos SIL, Charis SIL)
Don’t
- Expect a named HTML entity—none exists for ɹ
- Use plain
r(U+0072) when you mean the IPA alveolar approximant - Confuse ɹ (turned r) with ɼ (long leg) or ɻ (fishhook)
- Use
U+00279or CSS\00279—the correct code isU+0279and\279 - Put CSS escape
