🧠 How It Works

1

Hexadecimal Code

&#x016D; uses the Unicode hexadecimal value 016D to display the character. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#365; uses the decimal Unicode value 365 to display the same character. A common method for Latin Extended-A characters.

Named Entity

4

CSS Entity

Same visual result

All four methods produce the glyph: ŭ. Unicode U+016D sits in Latin Extended-A. Uppercase equivalent: U+016C (&Ubreve;). Do not confuse with plain u (U+0075), 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+0075)

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 \0016D—the correct value is \016D
  • Put CSS escape \016D in HTML text nodes
  • Omit UTF-8 encoding on pages with extended Latin characters
