That's hilarious, that Terry has had to do enough ugliness with Marc encodings that he indeed can recognize 0xC2 off the bat as the Marc8 encoding it represents! I am in awe, as well as sympathy. If the record is in Marc8, then you need to know if Perl Batch::Marc can handle Marc8. If it's supposed to be able to handle it, you need to figure out why it's not. (leader byte says UTF-8 even though it's really Marc8?). If Batch::Marc can't handle Marc8, you need to convert to UTF-8 first. The only software package I know of that can convert from and to Marc8 encoding is Java Marc4J, but I wouldn't be shocked if there was something in Perl to do it. (But yes, as you can tell by the name, "Marc8" is a character encoding ONLY used in Marc, nobody but library people write software for dealing with it).
