Yes, that makes sense. Since GNU tar only has the case

     --opt=ARG            single-line doc string

where ARG can have 'Ä' or some other character. I'm not very familiar
with localization or multi-byte encodings, but I can try to come up
with a unit test with some inspiration from some other modules.
