> 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.
