Hi,
The two methods in PDCIDFontType2Embedder are "isolated" and both work
with a cidToGid map. You need to create that yourself, have a look at
Type0Font.java in the PDFDebugger subproject. The lower part of the
constructor calls readMap() which builds a table that has CID and GIDs
so you should modify that to your need.
When done, you should check your file not just with PDFBox preflight but
also with verapdf.
If you need more help, please share your file (upload to sharehoster)
and the code you've written. I suspect you may have to add CID 0 manually.

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!

What exactly is your assignment? Convert some files so that they are
PDF/A-1b? Because you wrote "I'm trying to convert" but not to what.
Is it just that one file, or many?
Making files PDF/A compatible isn't just fixing some fonts... there may be
many issues. Callas and PDF-Tools have software for that.
Re the two issues you mention, this would require to create the two items
(CIDToGIDMap and CIDSet) from the existing font subset. Would be some hours
of work, but possible... maybe look at the file with PDFDebugger whether the
font shows something useful re GIDs. See also PDCIDFontType2Embedder for how
it is calculated...
What you did likely didn't work because it was subsets.

Hi, I'm new to pdfbox. I'm trying to convert an existing PDF which
uses an embedded OpenSans font
(https://fonts.google.com/specimen/Open+Sans) and receive these errors
from preflight:
3.1.9: Invalid Font definition, FZUADF+OpenSans: mandatory CIDToGIDMap
missing
3.1.11: Invalid Font definition, FZUADF+OpenSans: The CIDSet entry is
missing for the Composite Subset
Everything else seems to be fine, but for these I don't really have a
starting point. I can modify the source font (TTF file) if I have to,
the question would be how to do that and what exactly.
I also tried to just replace the embedded font with a new one
(basically iterate through PDF pages, get the resources, replace fonts
with my new ones) which "fixes" the error but results in a garbage
document not displaying valid text.
Any advice would be very welcome :)
