I'm looking at the script. From the comments it looks like Francois'
code is converting from ISO 5426 to ISO 8859-1. How are character sets
handled in UNIMARC? I'm guessing there are more character sets than ISO
5426 which can be used.

I just checked and Perl's Encode::* modules don't seem to handle ISO 5426 :( 
which is a shame. It is even more a shame that ISO doesn't make these standards public. I'm going to subscribe to perl-unicode@perl.org and see if I can find 
out more.

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.
