Use Cases

The uppercase U tilde (Ũ) is commonly used in:

🇻🇳 Vietnamese

Capital form in words like NGŨ (five/sleep), VŨ (dance), TRŨ (pillar) for headlines, signage, and localized UI.

🌍 African Orthographies

Some African language writing systems use U tilde as a distinct letter in romanization.

📝 Proper names

Vietnamese and African place names, surnames, and brands that include Ũ must display correctly.

🔤 Education

Language learning apps, dictionaries, and pronunciation guides teaching Vietnamese tones.

📄 Publishing

Legal, academic, and editorial content in Vietnamese requiring correct tone marks.

🌐 Internationalization

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

⚙ Programmatic HTML

When building HTML from i18n data, using &Utilde; or &#360; guarantees correct output.

💡 Best Practices

Do

  • Use &Utilde; in HTML when possible for readability
  • Serve pages as UTF-8; you can also type Ũ directly in UTF-8 source
  • Set lang="vi" on Vietnamese content for correct pronunciation
  • Use fonts that support Latin Extended-A and Vietnamese tone marks
  • Distinguish Ũ (tilde) from Ü (umlaut) and plain U

Don’t

  • Confuse Ũ with Ü (&Uuml;) or plain U when the tilde is required
  • Use the old incorrect CSS escape \00168—the correct value is \0168
  • Put CSS escape \0168 in HTML text nodes
  • Substitute plain U plus a combining tilde 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

&Utilde;
2

Or use hex/decimal references when escaping is needed

&#x0168; &#360;
3

For CSS stylesheets, use the escape in the content property

\0168
