Regarding my comment about base14 fonts you should create fonts this way:
doc->CreateFont( name.toLocal8Bit().data(), bold,
italic , false,
PdfEncodingFactory::GlobalIdentityEncodingInstance(),
PdfFontCache::eFontCreationFlags_None );
Default is PdfFontCache::eFontCreationFlags_AutoSelectBase14 which will
create base14 font when font name is for example "Helvetica", "Courier" or
"Times-Roman" and this will not work well with identity encoding.
Also you would probably want to use font subsetting for your use case for
smaller pdf. I am not sure if this is working well in podofo 0.9.6:
PdfDocument::CreateFontSubset
