This is indeed possible.
Apple made a mistake when they assigned encodings (scripts they call
them). They only allowed for 31 of them. This means that there aren't
enough. So there are at least five encodings for latin letters and they
are distinguished by language id
     icelandic
     turkish
     croatian
     romanian
     (everything else for the standard macroman)

Those would all use the standard macroman encoding

I have not.
