For some reason the Stage MARC Records for Import screen asks for MARC flavor when it should be asking for character encoding (the label is correct, but the options are not). There is nothing the tool can do with MARC flavor, as UNIMARC cannot be converted into MARC21 or vice versa by Koha. However, libraries do need to be able to specify the encoding of files they're importing since Koha guesses wrong when working with non-Roman MARC-8 encoded records.
