We might have done that deliberately, font files were usually copyrighted at the time we created PDF exporter... We'll have in mind an option for next release, in case you'd want to use it with free fonts (e.g. https://developers.google.com/fonts).

Just testing with Edge, our default font, Segoe UI, does not work, and neither does Arial. Acrobat seems to read both files OK.  The code we use to generate the files looks a bit like this...

                    var pdf = new PdfExporter();

                    try
                    {
                        pdf.AutoDetectEncoding = false;
                        pdf.DefaultEncoding = Encoding.Unicode;

                        pdf.Export(FlowChart, dlg.FileName);
                    }

                    catch (Exception ex)
                    {
                        ErrorBox(Resources.String_WriteFileFailed + ex.Message);
                    }

Both Arial and Segoe UI seemed to be installed locally.
