The problem related by Bug 18533 is also concerning all calls to MARC::Record->new_from_usmarc (this function uses MARC::Record->encoding). All imported marc notice from z3950 with 18152 active (versions after 16.11) are not considered as UTF-8 anymore by MARC::Record->new_from_usmarc and are also false encoded when imported in Koha. Example of problematic call: cataloguing/addbiblio.pl 85 my $record = MARC::Record->new_from_usmarc($marc);
