Sorry, but i've more deeply looked at francois code, and some MARC21 and
UNIMARC files.

My conclusion is that the following code :
        s/\xe1/\xc1/gm;
        s/\xe2/\xc2/gm;
        s/\xe3/\xc3/gm;
        s/\xe4/\xc4/gm;
        s/\xe8/\xc8/gm;
        s/\xe9/\xc9/gm;
        s/\xf0/\xd0/gm;
is enough to migrate from MARC21 to UNIMARC char coding. It tried this
on my marc21->unimarc script, on 30 000 records, and it works fine.

So, i think we have 2 complete tables (marc21 and unimarc) in Biblio.pm,
that i commited a few minuts ago.
