💡 Best Practices

Do

  • Place the combining mark after the base letter
  • Use fonts with extended Latin / IPA support for reliable rendering
  • Distinguish U+0340 (tone) from U+0300 (accent)
  • Use precomposed letters when your locale standard prefers NFC forms
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Assume U+0340 replaces locale-specific tone marks (e.g. Vietnamese uses other code points)
  • Confuse tone mark U+0340 with backtick U+0060
  • Put the combining mark before the base letter
  • Put CSS escape \340 in HTML text nodes
  • Expect a named HTML entity for U+0340
