Uppercase F Hook (Ƒ) is the Latin Extended-B character at Unicode U+0191 (LATIN CAPITAL LETTER F WITH HOOK). There is no named HTML entity. Use hex or decimal codes for African orthographies and phonetic text.

Not the same F · ƒ (ƒ)
Hex, decimal, CSS, and a typed character all produce the same glyph: Ƒ. Prefer Ƒ in HTML markup. For plain capital F see uppercase F; for the lowercase pair see lowercase F hook (ƒ, U+0192).
Built with Hex: Ƒ
Built with Decimal: Ƒ
Built with CSS: Ƒ
Typed: Ƒ
Case pair: Ƒ / ƒ
How It Works
1. Hex:Ƒ inserts Unicode U+0191 → Ƒ. Prefer this when there is no named entity.
2. Decimal: same code point as 401 → Ƒ. Same visual as hex.
3. CSS: use \0191 in content (not an HTML entity). #point::after appends Ƒ.
4. Typed: paste Ƒ in a UTF-8 document, or write Case pair: Ƒ / ƒ.
Pitfalls & Tips
Common mistakes when working with Uppercase F Hook.
Named
No named entity for Ƒ
Do not invent &Fhook; or reuse ƒ for uppercase. Use Ƒ or Ƒ only.
Look-alikes
Ƒ ≠ F ≠ ƒ
Hooked F is Ƒ. Plain Latin is F. Lowercase florin/function is ƒ. Match the orthography you need.
A11y
Prefer precomposed
Use U+0191 rather than inventing a look-alike from F plus decoration. One code point is clearer for search and screen readers.
Fonts
Glyph coverage
Latin Extended-B coverage varies. Prefer fonts with linguistic / African-script support and test on mobile.
CSS vs HTML
Do not mix escapes
\0191 belongs in CSS. Ƒ / Ƒ belong in HTML. Keep the leading zeros in \0191.
Semicolon
End references
Always finish with ; — write Ƒ, not Ƒ.

Frequently Asked Questions
Use Ƒ (hex), Ƒ (decimal), or the CSS escape \0191 in the content property. All render Ƒ. Prefer Ƒ for readable markup. There is no named HTML entity.
U+0191 (LATIN CAPITAL LETTER F WITH HOOK). Hex 0191, decimal 401. 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+0191. Use Ƒ or Ƒ instead. The lowercase f hook (U+0192) has ƒ, but that is a different character.
U+0191 is capital F with a hook. U+0046 is plain capital F. U+0192 is the lowercase f with hook (also used as florin / function symbol, named ƒ).
Use it for African orthographies, phonetic notation, and extended Latin text that needs capital F with hook — not as a substitute for plain F or ƒ.
HTML entities (Ƒ or Ƒ) go in markup. The CSS escape \0191 is used in stylesheets (usually in the content property of ::before/::after). Both render Ƒ.
