HTML markup
2

💡 Best Practices

Do

  • Use &ycirc; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type ŷ directly in UTF-8 source
  • Set lang="cy" on Welsh content for correct pronunciation
  • Use fonts that support Latin Extended-A characters
  • Distinguish ŷ (circumflex) from plain y and ý (acute)

Don’t

  • Substitute plain y when ŷ is required for correct Welsh spelling
  • Confuse ŷ (circumflex) with ý (acute) or ŵ (w circumflex)
  • Use the old incorrect CSS escape \00177—the correct value is \0177
  • Put CSS escape \0177 in HTML text nodes
  • Omit UTF-8 encoding on pages with accented characters
