DigiCert: & character in a printableString in ICA

DigiCert identified an issue with three Intermediate Certificate Authorities (ICAs) that improperly encoded an '&' character in the organization name as a PrintableString instead of UTF8String, violating RFC 5280 requirements. The problem was discovered during internal audits prompted by discussions on Mozilla forums. The affected certificates were revoked, and DigiCert is enhancing their linter for key ceremonies to prevent future occurrences.
