HTML markup
2

Decimal HTML Code

&#251; uses the decimal Unicode value 251 to display the same character. A common method when a numeric reference is needed.

Use Cases

The lowercase u circumflex (û) is commonly used in:

🇫🇷 French

Essential for correct spelling in words like sûr, dû, and jeûne. The circumflex often marks a historical omitted letter such as s.

🇰🇿 Kurdish

û is a distinct vowel in Kurdish Latin orthography and appears in native words and place names.

🌐 Multilingual Sites

Dictionaries, place names, product localization, and any content requiring proper accented characters.

📚 Language Learning

French and Kurdish courses, textbooks, and glossaries showing correct spelling with û.

♿ Accessibility

Using the correct character (U+00FB) with proper lang attributes ensures assistive technologies pronounce content correctly.

🔤 Linguistics

Phonetic transcription and linguistic descriptions using the circumflex diacritic over u.

🎨 CSS Generated Content

Using \00FB in the CSS content property to insert û via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type û directly in UTF-8 source
  • Use &ucirc; for readable HTML when a named form is preferred
  • Set lang attributes (e.g. lang="fr", lang="ku") on language-specific content
  • Use \00FB in CSS content when generating the symbol via pseudo-elements
  • Distinguish û (circumflex) from ú (acute), ù (grave), and ü (diaeresis)

Don’t

  • Substitute plain u when û is required in French or Kurdish text
  • Confuse û (circumflex) with ú (acute), ù (grave), ü (diaeresis), or plain u
  • Use the old incorrect CSS escape \000FB—the correct value is \00FB
  • Put CSS escape \00FB in HTML text nodes
  • Double-encode entity references in dynamically generated HTML
