Definition

What Is Uppercase Ou?

Uppercase Ou (Ȣ) is the Latin Extended-B character at Unicode U+0222 (LATIN CAPITAL LETTER OU). It is a single precomposed ligature letter, not two separate letters. There is no named HTML entity — use hex or decimal codes for medieval Latin, African orthographies, and linguistic text.

Remember

Character     Ȣ
Unicode       U+0222
Named entity  (none)
Hex entity    &#x0222;
Decimal       &#546;
CSS escape    \0222
Not the same  OU · Ö · Ƣ · ȣ

Hex, decimal, CSS, and a typed character all produce the same glyph: Ȣ. Prefer Ȣ in HTML markup. For the lowercase pair see ȣ (U+0223). Do not confuse this with the digraph OU, with Ö, or with Ƣ (oi).

Four ways to produce Ȣ, plus the case pair.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase Ou (Ȣ)</title>
  <style>
    #point::after {
      content: "\0222";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x0222;</p>
  <p>Using HTML Code: &#546;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Typed directly: Ȣ</p>
  <p>Case pair: Ȣ / ȣ</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex / decimal: U+0222 → Ȣ or Ȣ. The browser turns either into Ȣ.

2. Typed: in a UTF-8 document you can paste Ȣ directly — same glyph, no entity.

3. CSS: use \0222 in content (not an HTML entity). #point::after appends that Ȣ after the paragraph text.

4. Case pair: lowercase is U+0223 (ȣ) — see lowercase ou.

Pitfalls & Tips

Common mistakes when working with Uppercase Ou.

Named?

No named entity

HTML5 does not define a name for Ȣ. Use Ȣ or Ȣ.

Not the digraph OU

Typing O then U creates two characters. Ȣ is one code point — use it only when the source requires the ligature.

Not O with umlaut

U+00D6 (Ö, Ö) is a different letter. See uppercase O umlaut.

Fonts

Need Latin Extended-B coverage

Some fonts omit U+0222. Prefer fonts that cover Latin Extended-B (U+0180–U+024F).

CSS vs HTML

Do not mix escapes

\0222 belongs in CSS strings. Ȣ / Ȣ belong in HTML.

Case

Case is significant

Ȣ (U+0222) and ȣ (U+0223) are different characters. Use the case your content requires.

Compatibility

Browser Support

Uppercase Ou (U+0222) and its entity forms (Ȣ, Ȣ, CSS \\0222) are supported in all mainstream browsers when the page is UTF-8 and the font covers Latin Extended-B.

✓ Universal support

Uppercase Ou (Ȣ)

Encode with hex, decimal, CSS escape, or type the character — same Unicode code point everywhere.

U+0222 / entities Full support

Bottom line: Prefer Ȣ in HTML text. Use Ȣ as an equivalent, and \\0222 only inside CSS content. Glyph display depends on font coverage.

Remember

Key Takeaways

Unicode: this letter is U+0222 (decimal 546) — glyph Ȣ.
HTML: use Ȣ / Ȣ — no named entity.
CSS: use \0222 inside content for generated text.
Watch out: Ȣ ≠ digraph OU ≠ Ö ≠ oi Ƣ.

One line: U+0222 → Ȣ / Ȣ / CSS \0222 (no named entity).

Frequently Asked Questions
