[A12n-Collab] Is the "Franc symbol" in actual use anywhere?

[Karl Pentzlin <mail-from-a12n@xxxxxxxxxx>]

Unicode contains a "French franc symbol" (U+20A3, ₣, like a F with a
second horizontal stroke).
Is this currency symbol in actual use anywhere (especially in the
countries using the CFA franc)?

(I need this information as I am designing an international keyboard
layout.)

Thank you in advance for any help.
