Definition

What Is the Uppercase Ae Entity?

Uppercase Ae (Æ) is the Latin-1 Supplement character at Unicode U+00C6 (LATIN CAPITAL LETTER AE). HTML5 names it Æ. Use it for Danish, Norwegian, and other Latin-script text that needs the AE ligature.

Remember

Character     Æ
Unicode       U+00C6
Named entity  &AElig;
Hex entity    &#xC6;
Decimal       &#198;
CSS escape    \00C6
Not the same  &aelig; (æ) · AE (two letters)

Named, hex, decimal, CSS, and a typed character all produce the same glyph: Æ. Prefer Æ or Æ in HTML markup. For the lowercase form see æ; for AE with acute see uppercase ae acute.

Five ways to display Æ in HTML and CSS.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Uppercase Ae (Æ)</title>
  <style>
    #point::after {
      content: "\00C6";
    }
  </style>
</head>
<body>
  <p>Built with Named: &AElig;</p>
  <p>Built with Hex: &#xC6;</p>
  <p>Built with Decimal: &#198;</p>
  <p id="point">Built with CSS: </p>
  <p>Typed: Æ</p>
  <p lang="da">Dansk: &AElig;BLE, L&AElig;RER</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: Æ is the HTML5 name for U+00C6 → Æ (case-sensitive: capital AE).

2. Hex: Æ inserts the same code point. Same visual as named.

3. Decimal: same code point as 198 → Æ.

4. CSS: use \00C6 in content (not an HTML entity). #point::after appends Æ.

5. Typed: paste Æ in a UTF-8 document, or write Danish text with Æ.

Pitfalls & Tips

Common mistakes when working with Uppercase Ae.

Named

Prefer `Æ`

The name is case-sensitive. Æ is Æ; æ is æ. Write AElig exactly.

Look-alikes

Æ ≠ æ ≠ AE

One ligature glyph is Æ. Lowercase is æ. Separate A+E is not the ash letter — use the ligature when the language requires it.

A11y

Use the real letter

Prefer precomposed Æ (or Æ) over faking it with AE. Screen readers and search treat the ligature correctly.

Fonts

Glyph coverage

Latin-1 Supplement is widely supported. Still set lang="da" (or the correct language) when the text is Danish or Norwegian.

CSS vs HTML

Do not mix escapes

\00C6 belongs in CSS. Æ / Æ / Æ belong in HTML.

Semicolon

End references

Always finish with ; — write Æ, not &AElig.

Compatibility

Browser Support

Uppercase Ae (U+00C6) and its entity forms (Æ, Æ, Æ, CSS \\00C6) are supported in all modern browsers. Glyph coverage is excellent for Latin-1.

✓ Universal encoding

Uppercase Ae (Æ)

Encode with named, hex, decimal, or CSS escape — or type Æ directly in UTF-8 HTML. Prefer Æ or Æ.

Remember

Key Takeaways

One line: U+00C6 → Æ / Æ / Æ / CSS \00C6.
