Jonathan, Karen is correct -- CR/LF are invalid characters within a MARC record. This has nothing to do if the character is valid in the set -- the format itself doesn't allow it. --TR -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Jonathan Rochkind Sent: Thursday, May 19, 2011 11:29 AM To: [log in to unmask] Subject: Re: [CODE4LIB] is this valid marc ? I wonder if it depends on if your record is in Marc8 or UTF-8, if I'm reading Karen right to say that CR/LF aren't in the Marc8 character set. They're certainly in UTF-8! And a Marc record can be in UTF-8. On 5/19/2011 2:27 PM, Jonathan Rochkind wrote: > Is it really true that newline characters are not allowed in a marc > value?
