Any idea how that U+f020 character had got in there in the first place?

Actually there is a possible solution: when translating a U+F0xx
character, first check whether the xx byte really is illegal in the
target charset. If it's not, it won't roundtrip correctly, so encode
the U+F0xx as a ^X sequence instead. Doesn't seem worth the effort
though.
