The letter Ƒ (minuscule: ƒ) is a letter of the Latin alphabet, based on the italic form of f; or on its regular form with a descender hook added. A very similar-looking letter, ⟨ʄ⟩ (a turned f with a hook), is used in the IPA for a palatal implosive.
The minuscule italic ƒ, also called the florin sign, is used as a symbol for several currencies, including the former Dutch guilder, the Aruban florin, and the Netherlands Antillean guilder. It can be found as italic in non-italic fonts.
The italic ƒ is, rarely, used to denote mathematical functions, or to indicate aperture in photography (e.g. ƒ/2.8) in place of the more common italic f (in serif fonts) or oblique f (in sans-serif fonts). In modern typography an italic or oblique f is generally preferred for these applications.
Appearance in computer fonts
Older fonts and character encodings included only the minuscule form for its use as an abbreviation. Unicode includes both the majuscule and the minuscule. Because of its origin, the italic ƒ (f with a hook) looks exactly like the italic f (f) in some typefaces. Ƒ and ƒ occupy code points U+191 and U+192 in Unicode respectively, and may be entered by appropriate input methods.
The character has been used on the Macintosh (where it is created by pressing ⌥ Opt+f) to mean folder, in particular as part of a folder name (for example, the game Bugdom, when included on some Mac OS 9 installations, had the folder name "Bugdom ƒ").
