💡 Best Practices

Do

  • Serve pages as UTF-8 for direct Unicode input
  • Use fonts that support Combining Diacritical Marks (e.g. Charis SIL, Doulos SIL)
  • Pick one style (hex or decimal) per project for consistency
  • Test IPA syllabic forms across browsers

Don’t

  • Put the combining mark before the base character
  • Confuse ̩ (below) with ̍ (above, U+030D)
  • Mix entity styles randomly in one file
