📝 Linguistics & Phonetics

📚 Documentation

Tutorials on HTML entities, Unicode, or linguistic symbols showing numeric codes for Ȱ.

🎨 CSS Generated Content

Using \0230 in the CSS content property to insert Ȱ via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ȱ directly in UTF-8 source
  • Use numeric references (&#x0230; or &#560;) when escaping is required
  • Use \0230 in CSS content when generating the symbol via pseudo-elements
  • Use fonts that support Latin Extended-B characters
  • Distinguish Ȱ from Ȯ (dot only) and Ō (macron only)

Don’t

  • Expect a named HTML entity—none exists for Ȱ
  • Confuse Ȱ (dot + macron) with Ȯ (dot above), Ō (macron), or plain O
  • Combine separate diacritics when the precomposed Ȱ is required
  • Put CSS escape \0230 in HTML text nodes
  • Use \00230 in CSS—the correct escape is \0230
