Hi,
I'm looking into using Spire.Doc to save our correspondence to .pdf documents. Regulations require we use pdf/A-1a (or pdf/UA, but that's not available in Spire.Doc). Saving the docx with PdfConformanceLevel.Pdf_A1A doesn't seem to work however, all the text vanishes from the .pdf and the only things I see are the outlines of tables and other graphical elements.
I tried to save the same docx to regular pdf and to pdf/A-1b and those come out fine. It's just the pdf/A-1a that's all wrong. Any idea how I can fix this?
