Hi Tilman, thanks for your quick reply.
The goal is indeed to create PDF/A documents. It is just a single file. I was able to fix/bypass all other issues reported, the only remaining ones are those I mentioned. Regarding > this would require to create the two items (CIDToGIDMap and CIDSet) from the > existing font subset. Can you give me some idea on how to do that? I saw the code in PDCIDFontType2Embedder but not sure how to "apply" it to my existing PDF. Thanks a lot!
