🧠 How It Works

1

Hexadecimal Code

&#x016E; uses the Unicode hexadecimal value 016E to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#366; uses the decimal Unicode value 366 to display the same character. A common method for Latin Extended-A characters.

3

Named Entity

&Uring; is the standard named entity for Ů—readable in source HTML and part of the HTML5 entity set.

CSS Entity

\016E 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: Ů. Unicode U+016E sits in Latin Extended-A. Lowercase equivalent: U+016F (&uring;). Do not confuse with plain U (U+0055) or Å (A with ring).

Use Cases

The uppercase U ring above (Ů) is commonly used in:

🇨🇿 Czech

Capital form in Czech orthography (KŮŇ, DŮM) for headlines, signage, and localized UI. Represents the Czech long u sound.

📝 Proper names

Czech place names, surnames, and brands that include Ů must display correctly for accessibility and SEO.

🌐 Internationalization

Czech-language websites, forms, and CMS content requiring correct orthography.

🔤 Education

Language learning apps, dictionaries, and pronunciation guides teaching Czech spelling.

📄 Publishing

Legal, academic, and editorial content in Czech requiring the ring-above U letter.

🎨 Typography

Headlines, logos, and styled text in Czech requiring correct spelling.

⚙ Programmatic HTML

When building HTML from i18n data, using &Uring; or &#366; guarantees correct output.

💡 Best Practices

Do

  • Use &Uring; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ů directly in UTF-8 source
  • Set lang="cs" on Czech content for correct pronunciation
  • Use fonts that support Latin Extended-A characters
  • Distinguish Ů (ring) from plain U (U+0055) and Ú (acute)

Don’t

  • Confuse Ů with plain U, Ú (&Uacute;), or Å (&Aring;) when the ring-above u is required
  • Use the old incorrect CSS escape \0016E—the correct value is \016E
  • Put CSS escape \016E in HTML text nodes
  • Substitute plain U plus a combining ring when the precomposed letter is required
  • Double-encode numeric references in dynamically generated HTML

Key Takeaways

1

Use the named entity for readability in HTML source

&Uring;
2

Or use hex/decimal references when escaping is needed

&#x016E; &#366;
3

For CSS stylesheets, use the escape in the content property

\016E
