Not the same Õ · Ō · ȭ
Prefer Ȭ or Ȭ in HTML markup. You can also type Ȭ in UTF-8. There is no named entity. For the lowercase letter, use U+022D (ȭ).

Using CSS Entity: Ȭ
Typed directly: Ȭ
Not Õ (tilde only) or Ō (macron only)
How It Works
1. Hex:U+022C → Ȭ in HTML. The browser turns it into Ȭ.
2. Decimal: same code point as 556 → Ȭ. Same result as hex.
3. CSS: use \022C in content (not an HTML entity). #point::after appends that Ȭ after the paragraph text.
4. Typed / compare: paste Ȭ in UTF-8. Keep Õ (tilde only) and Ō (macron only) as separate characters.
Pitfalls & Tips
Common mistakes when working with U+022C.
Named
No &O…; name
HTML5 has no named entity for U+022C. Use Ȭ or Ȭ — do not invent a name.
vs Õ
Not tilde alone
Õ (Õ) has the tilde above but no macron. Ȭ needs both marks.
vs Ō
Not macron alone
Ō (Ō) is long Ō with no tilde. Do not swap the two.
vs ȭ
Case matters
Ȭ is capital. ȭ is lowercase. Use the matching code point for each case.
Encoding
Keep UTF-8 declared
Latin Extended-B letters display reliably with <meta charset="UTF-8">. Prefer numeric entities when encoding is uncertain.
CSS vs HTML
Do not mix escapes
\022C belongs in CSS strings. Ȭ / Ȭ belong in HTML.
A11y
Use real language context
When Ȭ appears in linguistic examples, label the purpose clearly so readers know it is a notation glyph, not everyday orthography.

Use it for linguistic, phonetic, or academic text that needs capital Ȭ as one precomposed letter — not as a substitute for plain Õ or Ō.
HTML entities (Ȭ or Ȭ) go in markup. The CSS escape \022C goes in stylesheet strings (usually content on ::before/::after).
