Uppercase Ae Acute (Ǽ) is the Latin Extended-B character at Unicode U+01FC (LATIN CAPITAL LETTER AE WITH ACUTE). There is no named HTML entity. Use hex or decimal codes for Old Norse and extended Latin orthography.

Not the same Æ (Æ) · ǽ (lowercase)
Hex, decimal, CSS, and a typed character all produce the same glyph: Ǽ. Prefer Ǽ in HTML markup. For plain capital AE see Æ; for the lowercase acute pair see lowercase ae acute (U+01FD).
Built with Hex: Ǽ
Built with Decimal: Ǽ
Built with CSS: Ǽ
Typed: Ǽ
Case pair: Ǽ / ǽ
How It Works
1. Hex:Ǽ inserts Unicode U+01FC → Ǽ. Prefer this when there is no named entity.
2. Decimal: same code point as 508 → Ǽ. Same visual as hex.
3. CSS: use \01FC in content (not an HTML entity). #point::after appends Ǽ.
4. Typed: paste Ǽ in a UTF-8 document, or write Case pair: Ǽ / ǽ.
Pitfalls & Tips
Common mistakes when working with Uppercase Ae Acute.
Named
No named entity
Do not invent names like Æacute;. Use Ǽ or Ǽ. Plain AE is Æ (no acute).
Look-alikes
Ǽ ≠ Æ ≠ ǽ
Acute AE is Ǽ. Plain capital AE is Æ. Lowercase acute is ǽ. Match case and accent to the orthography.
A11y
Prefer precomposed
Use U+01FC rather than Æ + combining acute when possible — one code point is clearer for search and screen readers.
Fonts
Glyph coverage
Latin Extended-B coverage varies. Prefer fonts with linguistic support and test on mobile.
CSS vs HTML
Do not mix escapes
\01FC belongs in CSS. Ǽ / Ǽ belong in HTML. Keep the leading zero in \01FC.
Semicolon
End references
Always finish with ; — write Ǽ, not Ǽ.

U+01FC (LATIN CAPITAL LETTER AE WITH ACUTE). Hex 01FC, decimal 508. It belongs to Latin Extended-B (U+0180–U+024F). There is no named HTML entity.
No. HTML5 does not define a named entity for U+01FC. Use Ǽ or Ǽ instead. Plain AE uses Æ (U+00C6).
U+01FC is capital AE with an acute accent. U+00C6 (Æ) is plain capital AE with no acute. U+01FD is the lowercase ae with acute.
Use it for Old Norse, linguistic notation, and extended Latin orthography that needs capital Æ with acute — not as a substitute for plain Æ.
HTML entities (Ǽ or Ǽ) go in markup. The CSS escape \01FC is used in stylesheets (usually in the content property of ::before/::after). Both render Ǽ.
