Bookmarks are being output with a special character

Aspose.PDF Product Family

I am creating a simple bookmark into this PDF using Aspose.PDF version 25.3.0.0:

            Document newDoc = new Document();
            newDoc.Pages.Add();

            var pdfOutline = new Aspose.Pdf.OutlineItemCollection(newDoc.Outlines);
            pdfOutline.Title = "Test Outline";
            pdfOutline.Action = new Aspose.Pdf.Annotations.GoToAction(newDoc.Pages[1]);

            newDoc.Outlines.Add(pdfOutline);

            newDoc.Save("test.pdf");

However, when I extract the bookmark using an older version of Aspose (19.1.0.0)

            PdfBookmarkEditor bookmarkEditor = new PdfBookmarkEditor();
            bookmarkEditor.BindPdf(newDoc);

            Bookmarks bookmarks = bookmarkEditor.ExtractBookmarks();
            Console.WriteLine(bookmarks[0].Title);
            //output is ÿþTest Outline

The output of the Title contains a few special characters in the beginning. “ÿþTest Outline”
Why are there special characters being output from the older version of Aspose and how can i fix it without upgrading the old version of aspose (19.1.0.0)?
I tried extracting the bookmark with other PDF libraries as well and they also output it with the special characters “ÿþ” at the beginning of each bookmark.

Have you tried extracting the bookmarks using the latest version of the API? Is it also extracting them with special characters? Please share the PDF that you have generated in your environment with the above code you shared. We will test it in our environment and address the issue accordingly.

I have tried using the latest version of the Aspose.PDF API and it works fine, no issues. But I have other programs that use other PDF libraries and also an older version of Aspose.PDF (19.1.0.0) that experience this issue.

Attached is a sample of the PDF.

We provide support on the basis of the latest version of the API and we are afraid that we cannot test or address an issue that is happening with such an older version. Please note that a lot of changes and fixes have been made to the API since then. We recommend that you update to the latest version in your applications running Aspose.PDF and if you face any issues still, please feel free to let us know.
