Tilman.
Using embedSubset to false I get another problem.
The instruction
pageResources.getFont(fontName);
issues following warning:
Apr 14, 2017 12:08:18 PM org.apache.pdfbox.pdmodel.font.PDCIDFontType2 <init>
INFO: OpenType Layout tables used in font ArialMT are not implemented in PDFBox
and will be ignored
And then the font isn't deleted from the file (but the code runs without any
error/exception)...
pdFont.getName() is "ArialMT", and it contains the COSName with key "FontFile2"

I would have to see the file to find out what went wrong. And an itext
generated file as well, if possible.
Btw "AAAEOG+ArialMT" means you used a subset. Avoid doing that, i.e. set the
embedSubset parameter to false. This way PDFBox will embed the full font, which
you'll delete later.
