Uppercase O with dot above and macron (Ȱ) is the Unicode character at U+0230 in Latin Extended-B. Official name: LATIN CAPITAL LETTER O WITH DOT ABOVE AND MACRON — a capital O with both a dot above and a macron, used in linguistic and phonetic notation.

Not the same ȱ · Ō · Ȯ
Prefer Ȱ or Ȱ in HTML markup. You can also type Ȱ in UTF-8. The lowercase pair is ȱ (U+0231). HTML5 has no named entity for either form.

Case pair: Ȱ / ȱ
How It Works
1. Hex:U+0230 → Ȱ in HTML. Preferred numeric form when you need an entity.
2. Decimal: same code point as 560 → Ȱ. Same glyph as hex.
3. CSS: use \0230 (four hex digits) in content. Shorter forms can be misread by the CSS parser. #point::after appends that Ȱ.
4. Typed / pair: paste Ȱ in UTF-8, or show both cases with Ȱ / ȱ.
5. No named entity: HTML5 does not define a name for U+0230 — use numeric references or type the character. Ō is macron-only Ō, not Ȱ.
Pitfalls & Tips
Common mistakes when working with U+0230.
Named
No named HTML entity
There is no named entity for U+0230. Use Ȱ or Ȱ.
vs Ō
Not macron only
Ō (Ō) has a macron only. Ȱ has both a dot above and a macron.
vs Ȯ
Not dot above only
Ȯ is O with dot above. Ȱ adds the macron as well — do not swap them.
Encoding
Keep UTF-8 declared
Latin Extended-B letters display reliably with <meta charset="UTF-8">. Prefer numeric entities when the source file encoding is uncertain.
CSS vs HTML
Do not mix escapes
\0230 belongs in CSS strings. Ȱ / Ȱ belong in HTML.
Fonts
Coverage varies
Some UI fonts omit less-common Latin Extended-B glyphs. Test Ȱ in your target fonts.
Compatibility
Browser Support
Uppercase O with dot above and macron (U+0230) and its entity forms (Ȱ, Ȱ, CSS \\0230) are supported in all mainstream browsers. Visible glyphs depend on Latin Extended-B font coverage.
✓ Universal support
Uppercase O Above Dot Macron (Ȱ)
Encode with hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer Ȱ or Ȱ in HTML (no named entity). Use \\0230 only inside CSS content. Do not confuse with macron Ō or dot-above Ȯ.
Remember
Key Takeaways
Unicode: uppercase O with both marks is U+0230 (decimal 560) — glyph Ȱ.
HTML: no named entity — use Ȱ / Ȱ or type the character.
CSS: use \0230 (four hex digits) inside content.
Meaning:Ȱ is both marks — not ȱ (lower), not Ō (macron), not Ȯ (dot only).
One line:U+0230 → Ȱ / Ȱ / CSS \0230 (no named entity).
Frequently Asked Questions
Use Ȱ (hex), Ȱ (decimal), type Ȱ directly in UTF-8, or the CSS escape \0230 in content. There is no named HTML entity.
U+0230 (LATIN CAPITAL LETTER O WITH DOT ABOVE AND MACRON). Hex 0230, decimal 560. It belongs to Latin Extended-B (U+0180–U+024F).
No. Use numeric references Ȱ or Ȱ, or type Ȱ in UTF-8.
No. Ȱ is U+0230 (capital with both marks). ȱ is U+0231 (lowercase). Ō is U+014C (Ō, macron only).
Use it for linguistic or phonetic notation that needs capital O with both a dot above and a macron — not as a substitute for plain O, Ó, or Ō alone.
HTML entities (Ȱ or Ȱ) go in markup. The CSS escape \0230 goes in stylesheet strings (usually content on ::before/::after). Prefer four hex digits in CSS.
