I tried PDF/A a while back and noticed the XMP header has an extra byte order mark which validators flagged as “??”.
I’ve attached the patch I used to remove it, however I’m still on an old version of ConTeXt so this might not apply cleanly to yours. You might need to open the patch in a hex editor to see the difference in the two lines as most text editors will not show the BOM. -- Leo On Fri, 2 Nov 2018 at 20:12, luigi scarso <luigi.sca...@gmail.com> wrote: > > > Il giorno ven 2 nov 2018, 19:06 Rik Kabel <cont...@rik.users.panix.com> > ha scritto: > >> The example file in the wiki (at https://wiki.contextgarden.net/PDF/A) >> no longer verifies as compliant PDF/A.
