What You'll Learn

How to display the uppercase O with breve (Ŏ) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+014E (LATIN CAPITAL LETTER O WITH BREVE) in the Latin Extended-A block. The breve is a curved diacritical mark used in Slavic languages and phonetic notation.

Render it with Ŏ, Ŏ, or CSS escape \014E. There is no named HTML entity for this character. In UTF-8 documents you can also type Ŏ directly. Do not confuse with Romanian Ă (Ă), which uses breve on A, not O.

🎨 CSS Generated Content

Using \014E in the CSS content property to insert Ŏ via pseudo-elements.

💡 Best Practices

Do

  • Serve pages as UTF-8; you can type Ŏ directly in UTF-8 source
  • Use numeric references (&#x014E; or &#334;) when escaping is required
  • Use \014E in CSS content when generating the symbol via pseudo-elements
  • Use fonts that support Latin Extended-A characters (U+0100–U+017F)
  • Distinguish Ŏ (breve) from Ó (acute) and Ǒ (caron)

Don’t

  • Expect a named HTML entity—none exists for Ŏ
  • Confuse Ŏ (O breve) with Ă (A breve used in Romanian)
  • Confuse Ŏ (breve) with Ǒ (caron), Ó (acute), or plain O
  • Put CSS escape \014E in HTML text nodes
  • Use \0014E in CSS—the correct escape is \014E

Key Takeaways

1

Type Ŏ directly, or use hex/decimal references

&#x014E; &#334;
2

For CSS stylesheets, use the escape in the content property
