🧠 How It Works
Hexadecimal Code
Ȭ uses the Unicode hexadecimal value 022C to display the character. The x prefix indicates hexadecimal format.
Decimal HTML Code
Ȭ uses the decimal Unicode value 556 to display the same character. A common method when a numeric reference is needed.
Direct Character
Type Ȭ directly in HTML when your document uses UTF-8 encoding. There is no named entity for this letter.
CSS Entity
\022C is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

All methods produce the glyph: Ȭ. Unicode U+022C sits in Latin Extended-B. Lowercase equivalent: U+022D (ȭ). Do not confuse with Õ (tilde only), Ō (macron only), or Ȫ (diaeresis + macron).
Use Cases
The uppercase O tilde macron (Ȭ) is commonly used in:
Phonetic transcription marking both nasalization (tilde) and vowel length (macron) on O.
Scholarly papers, dictionaries, and critical editions requiring precise diacritic combinations.
Orthographic documentation and transliteration schemes that use the combined tilde-and-macron form.
Linguistics and language courses teaching diacritic notation and extended Latin characters.
Font specimens showcasing Latin Extended-B support for stacked diacritics.
Using U+022C ensures assistive technologies interpret the symbol correctly in academic content.
When building HTML from data, Ȭ or Ȭ guarantees correct output.
💡 Best Practices
Do
- Serve pages as UTF-8; you can type Ȭ directly in UTF-8 source
- Use numeric references (
ȬorȬ) when escaping is required - Use fonts that support Latin Extended-B (U+0180–U+024F)
- Distinguish Ȭ from Õ (tilde only), Ō (macron only), and Ȫ (diaeresis + macron)
- Use the precomposed Ȭ when both tilde and macron apply to the same O
Don’t
- Use Ȭ for Portuguese or Estonian text—use Õ (
Õ) instead - Substitute Õ or Ō when Ȭ is required in linguistic notation
- Stack separate combining marks when the precomposed Ȭ is the correct character
- Expect a named HTML entity—none exists for Ȭ
- Put CSS escape
