What Is the Lowercase U Circumflex Entity?

Lowercase u with circumflex (û) is the Latin-1 Supplement character at Unicode U+00FB (LATIN SMALL LETTER U WITH CIRCUMFLEX). The circumflex (^) sits above the letter. Common in French (sûr, dû) and other languages. HTML5 defines the named entity û.

Remember
Character     û
Unicode       U+00FB
Named entity  û
Hex entity    û
Decimal       û
CSS escape    \00FB

All of these produce the same glyph: û. Prefer û or a pasted û in UTF-8 pages; use numeric or CSS forms when you need them.

  <style>
    #point::after {
      content: "\00FB";
    }
  </style>
</head>
<body>

Try It Yourself

How It Works

1. Named: &ucirc; is the HTML5 named entity for U+00FB. Clearest form in HTML source.

2. Hex: U+00FB → &#x00FB; in HTML. Same glyph as named.

3. Decimal: same code point as 251 → &#251;. Same result.

4. CSS: use \00FB in content (not an HTML entity). #point::after appends that û after the paragraph text.

Pitfalls & Tips

Common mistakes when working with the u circumflex entity.

Named

Prefer &ucirc;

HTML5 defines a named entity for this letter — use it for readable HTML.

CSS vs HTML

Do not mix escapes

\00FB belongs in CSS. &ucirc; / &#x00FB; / &#251; belong in HTML.

Look-alikes

Not u or ü

Plain u is U+0075; u umlaut ü is U+00FC. Circumflex is a different diacritic.

Case

û vs Û

Uppercase is U+00DB (&Ucirc;) — a different code point from U+00FB.

Semicolon

End references

Always finish with ; — write &ucirc;, not &ucirc.

UTF-8

Declare charset

If you paste û directly, serve the page as UTF-8 with <meta charset="UTF-8">.

Key Takeaways

  • Unicode: u with circumflex is U+00FB (decimal 251), Latin-1 Supplement.
  • HTML: prefer &ucirc;, or use &#x00FB; / &#251;.
  • CSS: use \00FB inside content for generated text.
  • Use: French and Latin text with û — not the same as plain u or ü.

One line: U+00FB → &ucirc;, or &#x00FB; / &#251; / CSS \00FB.
