What Is Uppercase U Breve?

Uppercase U Breve (Ŭ) is the Latin Extended-A character at Unicode U+016C (LATIN CAPITAL LETTER U WITH BREVE). HTML5 names it Ŭ. Use it for Esperanto and other Latin-script text that needs Ŭ.

Remember
Character     Ŭ
Unicode       U+016C
Named entity  Ŭ
Hex entity    Ŭ
Decimal       Ŭ
CSS escape    \016C
Not the same  ŭ (ŭ) · U · Û · inverted breve

Named, hex, decimal, CSS, and a typed character all produce the same glyph: Ŭ. Prefer Ŭ or Ŭ in HTML markup. For the lowercase form see ŭ; for U with circumflex see uppercase U circumflex.

<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase U Breve (Ŭ)</title>
  <style>
    #point::after {
      content: "\016C";
    }
  </style>
</head>

How It Works

1. Named: &Ubreve; is the HTML5 name for U+016C → Ŭ (case-sensitive: capital U).

2. Hex / decimal: &#x016C; or &#364; insert the same code point.

3. Typed: in a UTF-8 document you can paste Ŭ directly — same glyph, no entity.

4. CSS: use \016C in content (not an HTML entity). #point::after appends that Ŭ after the paragraph text.

5. Case pair: lowercase is &ubreve; (U+016D, ŭ) — see lowercase U breve.

Pitfalls & Tips

Common mistakes when working with Uppercase U Breve.

Case

Named entity is case-sensitive

&Ubreve; is Ŭ. &ubreve; is ŭ. Do not mix them.

Plain U

Not the same as plain U

Plain U (U+0055) has no breve. Do not substitute it when Ŭ is required (for example in Esperanto).

Û

Not U with circumflex

U+00DB (Û, &Ucirc;) uses a circumflex, not a breve. See uppercase U circumflex.

Shape

Breve ≠ inverted breve

U+0216 (Ȗ) is capital U with inverted breve — a different mark. See uppercase U inverted breve.

Combining

Prefer the precomposed letter

Use U+016C instead of U + combining breve (U+0306) when the precomposed form is available.

CSS vs HTML

Do not mix escapes

\016C belongs in CSS strings. &Ubreve; / &#x016C; / &#364; belong in HTML.

Browser Support

Uppercase U Breve (U+016C) and its entity forms (&Ubreve;, &#x016C;, &#364;, CSS \\016C) are supported in all mainstream browsers when the page is UTF-8 and the font covers Latin Extended-A.

✓ Universal support

Uppercase U Breve (&#x016C;)

Encode with named, hex, decimal, CSS escape, or type the character — same Unicode code point everywhere.

Bottom line: Prefer &Ubreve; in HTML text. Use &#x016C; / &#364; as equivalents, and \\016C only inside CSS content. Glyph display depends on font coverage.

Key Takeaways

  • Unicode: this letter is U+016C (decimal 364) — glyph Ŭ.
  • HTML: prefer &Ubreve; — also &#x016C; / &#364;.
  • CSS: use \016C inside content for generated text.
  • Watch out: Ŭ ≠ plain U ≠ Û ≠ Ȗ ≠ ŭ.

One line: U+016C → &Ubreve; / &#x016C; / &#364; / CSS \016C.

Frequently Asked Questions

Use &Ubreve; (named), &#x016C; (hex), &#364; (decimal), or the CSS escape \016C in the content property. All render Ŭ. Prefer &Ubreve; or &#x016C; for readable markup.

Yes. HTML5 defines &Ubreve; for U+016C. It is case-sensitive — write Ubreve with a capital U. Lowercase &ubreve; is a different character (ŭ).

HTML entities (&Ubreve;, &#364;, or &#x016C;) go in markup. The CSS escape \016C is used in stylesheets (usually in the content property of ::before/::after). Both render Ŭ.
