And thanks for your answer. And all the links you pointed at.
But this puzzles me. Indeed, imho, and Paul agrees with me, I had rather keep all the characters used by a customer rather than modifying or dropping data. The problem is that French library or any non US-MARC library doesnot HAVE to use MARC-21 characters. They use ISO6937 or ISO5426, or latin1 or event directly UTF-8. So for them Having valid MARC-21 characters is not their goal. They want to keep their data safe. Woulditnot possible to add some feature to M::F::X which would allow people to collect UTF8 data as such without checking MARC21 ? -- Henri Damien LAURENT et Paul POULAIN Consultants indépendants en logiciels libres et bibliothéconomie (http://www.koha-fr.org)
