There's something about this that's tugging at my memory that hints it
might not be quite what the error message said as far as an invalid
unicode character.
I guess my first couple of questions:
1) What identifiers/records are you pulling? I didn't see any actual
examples in your email. Can you construct the url that the perl
script is doing and give it to us?
I'd guess it's very likely the original marc record is goofed up due
to some transforms. I've seen it from people doing really weird
things to records as part of the submit process to IA.
2) You're sure that is a unicode marc record and not marc-8, right?
3) What version is your MARC::Record module? Might want to upgrade if
it's old, there's been some bug fixes.
