Hello Horst, I just found that pdfcpu does not extract the text form "form1[0].Page1[0].P2_sf[0].P2_Ln305_sf[0].Ln305_inpt[0]" from the pdf https://www.canada.ca/content/dam/cra-arc/formspubs/pbg/t2sch141/t2sch141-fill-23e.pdf. However, pdfcpu is able to retrieve the value after decompressing the pdf document with pdftk.
