🧠 How It Works

1

Named Entity

&Uacute; is the standard named entity for Ú—readable in source HTML and part of the HTML Latin-1 entity set.

HTML markup
2

Hexadecimal Code

&#xDA; uses the Unicode hexadecimal value DA to display the character. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#218; uses the decimal Unicode value 218 to display the same character. A common method for Latin-1 characters.

CSS Entity

\00DA is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All four methods produce the glyph: Ú. Unicode U+00DA sits in Latin-1 Supplement. Lowercase equivalent: U+00FA (&uacute;). Do not confuse with plain U (U+0055), Ù (U grave), or Ü (U umlaut).

✅

Use Cases

The uppercase U acute (Ú) is commonly used in:

🇬🇤 Spanish Content

Sentence-initial words like Único, Último, and Útil for correct Spanish spelling.

🇧🇵 Portuguese

Used in Útil and Último when capitalized at the start of a sentence or title.

🇭🇺 Hungarian

📝 Proper names

🔤 Language learning

🔍 Search & SEO

Correct spelling improves screen reader pronunciation and search indexing.

💡 Best Practices

Do

  • Use &Uacute; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ú directly in UTF-8 source
  • Set lang attributes (e.g. lang="es" or lang="hu") for correct pronunciation
  • Use fonts that support Latin-1 Supplement characters
  • Distinguish Ú (U+00DA) from plain U (U+0055)—meaning can change in proper names

Don’t

  • Substitute plain U when Ú is required for correct spelling
  • Confuse Ú (u acute) with Ù (u grave, &Ugrave;) or Ü (u umlaut)
  • Put CSS escape \00DA in HTML text nodes
  • Use the old incorrect CSS escape \000DA—the correct value is \00DA
  • Omit UTF-8 encoding on pages with accented characters

Key Takeaways
