After adding text stamp error on opening PDF(C#)


I’ve got a PDF file. In C# .net, I add a text stamp on it according to

The file is successfully converted but when I try to open it with Adobe Acrobat Reader DC (v 2019.021.20061), I get the following error:

In the stamp, the text is displayed with bullets:

Could you please tell me what might be causing this issue?

I used the following code:
using Aspose.Pdf.Facades;
using Aspose.Pdf.Text;
using System;
using System.IO;
using System.Text;

public static void ToPdf(string sourcePath, string targetPath)
  var fileStamp = new PdfFileStamp();

  // Create stamp.
  var stamp = new Aspose.Pdf.Facades.Stamp();
  stamp.BindLogo(new FormattedText("Hello world!", System.Drawing.Color.Blue, System.Drawing.Color.Gray, "Arial", EncodingType.Winansi, true, 28));
  stamp.SetOrigin(200, 200);
  stamp.Rotation = 90.0F;
  stamp.IsBackground = false;

  // Add stamp to PDF file.
