Roberto Benedetti updated FOP-2910:
-----------------------------------
Description:
When creating PDF/A-2a or PDF/A-3a with font embedding mode "subset" the
resulting PDF in not valid according to veraPDF which reports:
??Specification: ISO 19005-3:2012, 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.??
Embedding the complete font seems to solve the validation error but resulting
files are very large.
When exporting files as PDF/A from Microsoft Word the PDF is valid and it only
contains a subset of the font.
The only difference I noticed is that Word does not create a CIDSet.
File [^samples.zip] contains two PDF/A-3a created by Word and the files used to
create the same PDFs with FOP.
