Hello,
thanks for your help I already looked a little bit deeper, after I
tried to use PDResources which could add font’s but if I add the font
in every page the file gets too big and if I only add the font at the
first page it won’t validate correctly.
If it is the same font, you can add the same COSStream object, i.e. you
don't have to create a new one.
About the size - that's why subsets are used. But for that, you would
have to analyse each content stream to see which glyphs are used.
It's probably cheaper to buy a product like callas pdfaPilot.

After that I looked at COS but I’m not that far yet, still thanks
after looking inside the source of pdfbox I will definitely find out
more things.

I know how to extract them, however adding them seems to be the
„bigger“ problem, since mostly I can’t just embed them with a
command. The problem relies on where I should put the font file,
currently I have a folder with all the necessary fonts and could
create font objects with that and also I know which fonts are
missing inside my pdf, but now the problem relies on attach the file
i.e. embed the font.
You need to understand the COS data types (COSDictionary, COSStream,
COSArray, COSBase etc), then insert a COSStream (that has your font
file) at the correct place in the font descriptor (type
COSDictionary) with the correct key. The key is FontFile1, FontFile2
or FontFile3 depending on the type of font.
