Hello. I have created PDF/A-2b document with pdfbox and I have found that the font subsetting provided by pdfbox doesn't match the following requirement from the specification:
Specification: ISO 19005-2:2011, Clause: 6.2.11.4, Test number: 4 If the FontDescriptor dictionary of an embedded CID font contains a CIDSet stream, then it shall identify all CIDs which are present in the font program, regardless of whether a CID in the font is referenced or used by the PDF or not. That is: some CIDs which are in the CIDToGidMap don't appear in the CIDSet. Maybe it is a bug or you can add an option to generate the CIDSet to be consistent with the CIDToGidMap. Additional details (including a sample pdf file) here: https://github.com/veraPDF/veraPDF-library/issues/907 I think that I can provide the code used to generate the sample pdf if needed. Esteban
