For African use as a Latin letter, it's unfortunate that most fonts show ƒ (LATIN SMALL LETTER F WITH HOOK) in italic style, as if it was a florin symbol. This letter should better be vertically straight, like an f with just the hook added below, and adopting an italic style only in italic fonts, not in roman fonts.
Only the florin sign should remain italic and thus disunified (its shape should not change significantly in italic fonts, as it could collide easily with surrounding digits or could become too large to fit in monospaced cells for digits with standard figure-width). A renderer using a font that does not have a mapping for the florin sign should be able to synthetize it by italicizing the vertical shape of the LATIN SMALL LETTER F WITH HOOK, or better by using the mapping of that letter in an italic variant font in the same font family. 2012/8/13 Michael Everson <ever...@evertype.com>: > On 13 Aug 2012, at 15:20, Leif Halvard Silli wrote: > >> Mac fonts also included ƒ (LATIN SMALL LETTER F WITH HOOK).
