Oups, I (erroneously) tried with accented characters, which explains my
answer. Actually, I (correctly) get "unknown" if using characters from
the ASCII set, so my understanding is that there's actually no problem
with the OP's request as there's no reason why "16-03-02" should be
represented as anything else than "unknown" according to this
information (all characters are in the ASCII set).
