Definition

What Is Uppercase U Acute?

Uppercase U Acute (Ú) is the Latin-1 Supplement character at Unicode U+00DA (LATIN CAPITAL LETTER U WITH ACUTE). HTML5 names it Ú. Use it for Spanish, Portuguese, Catalan, Hungarian, Czech, Slovak, and other Latin-script text that needs Ú.

Remember

Character     Ú
Unicode       U+00DA
Named entity  &Uacute;
Hex entity    &#xDA;
Decimal       &#218;
CSS escape    \00DA
Not the same  &uacute; (ú) · U · &Ugrave; · &Udblac;

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

Five ways to display Ú in HTML and CSS.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase U Acute (Ú)</title>
  <style>
    #point::after {
      content: "\00DA";
    }
  </style>
</head>
<body>
  <p>Built with Named: &Uacute;</p>
  <p>Built with Hex: &#xDA;</p>
  <p>Built with Decimal: &#218;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: Ú</p>
  <p lang="es">Case pair: &Uacute; / &uacute;</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: Ú is the HTML5 name for U+00DA → Ú (case-sensitive: capital U).

2. Hex / decimal: Ú or Ú insert the same code point.

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

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

5. Case pair: lowercase is ú (U+00FA, ú) — see lowercase U acute.

Pitfalls & Tips

Common mistakes when working with Uppercase U Acute.

Case

Named entity is case-sensitive

Ú is Ú. ú is ú. Do not mix them.

Plain U

Not the same as plain U

Plain U (U+0055) has no acute. Do not substitute it when Ú is required.

Not U with grave

U+00D9 (Ù, Ù) uses a grave, not an acute. See uppercase U grave.

Not U with double acute

U+0170 (Ű, &Udblac;) is common in Hungarian. See uppercase U double acute.

Combining

Prefer the precomposed letter

Use U+00DA instead of U + combining acute (U+0301) when the precomposed form is available.

CSS vs HTML

Do not mix escapes

\00DA belongs in CSS strings. Ú / Ú / Ú belong in HTML.
