🧠 How It Works

1

Hexadecimal Code

&#x016C; uses the Unicode hexadecimal value 016C to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#364; uses the decimal Unicode value 364 to display the same character. A common method for Latin Extended-A characters.

Same visual result

All four methods produce the glyph: Ŭ. Unicode U+016C sits in Latin Extended-A. Lowercase equivalent: U+016D (&ubreve;). Do not confuse with plain U (U+0055), Ú (u acute), or ů (u ring).

💡 Best Practices

Do

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

Don’t

  • Substitute plain U when Ŭ is required for correct spelling
  • Confuse breve Ŭ with acute Ú or ring ů
  • Use the old incorrect CSS escape \0016C—the correct value is \016C
  • Put CSS escape \016C in HTML text nodes
  • Omit UTF-8 encoding on pages with extended Latin characters

Key Takeaways

1

Four references render Ŭ; named entity is most readable

2

For CSS stylesheets, use the escape in the content property
