Ƒ

The letter F with hook (uppercase Ƒ, lowercase: ƒ) is a letter of the Latin script, based on the italic form of f; or on its regular form with a descender hook added.

A very similar-looking letter, ⟨ʄ⟩ (a dotless j with a hook and a horizontal stroke), is used in the IPA for a voiced 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.

[citation needed] It can be represented with U+1D453 𝑓 MATHEMATICAL ITALIC SMALL F. Older fonts and character encodings included only the minuscule form for its use as an abbreviation.

On a computer running Microsoft Windows and using the Windows-1252 character encoding, the minuscule can be input using alt+159 or alt+0131.

Lowercase F with a hook in regular type on the left and in italic on the right, the florin sign is always in italic.
