It was, however, usually only when the system or an app created a folder name that the ƒ was added. Humans creating a folder name seldom added it, I think.

No, humans learnt to do it. And we still do: it's right there on alt-f on the US/GB/IE keyboards. It's unfortunate that this italic character which is really the same thing as the florin sign was unified with the African Ƒƒ because I am sure it makes fonts tend to be unsuitable for African use. In fact Just looking at it in this e-mail I see that my own ƒ is not really suitable, as it should be as long as a j. fjƒɲ. I[m going to go fix that.

Less so than the ƒ, but many of us learnt to use the ƒ for our folder names.
