Hi,

String fontFileName = @"c:\windows\fonts\Arial.ttf";
   Spire.Pdf.PdfDocument doc = new Spire.Pdf.PdfDocument();
   doc.LoadFromFile(file);
   PdfUsedFont[] fonts = doc.UsedFonts;
   foreach (PdfUsedFont font in fonts)
   {
      PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(fontFileName, font.Size,font.Style);
      font.Replace(trueTypeFont);
   }
   doc.SaveToFile(@"c:\temp\output.pdf");

Hello,

After an initial test, our dev team found that there was unicode encoding in your pdf document. Becasue of this, the raplace operation might corrupt the inner chracter mapping and cause garbled data. Therefore, there might be no solution to your issue in a short time.
Sorry for the inconvenience caused.
