Junk characters added while converting DOCX to PDF

[sumanpadhy]

While trying to convert a DOCX to PDF, there are certain fields we are replacing and then we are creating the final PDF.
There is a random text which gets added as "khbdv" below the header. If the same docx document is saved directly, we cant see the same characters.
I have added the parameter list as UsePSCoversion = true, IsEmbeddedAllFonts = true.

Language: C#, Nuget Package version: 9.9.7, C# version: 7.3, .Net Framework 4.7.2

Hello,

Thank you for your inquiry.
I did an initial test but didn't reproduce your issue. I suggest you first try again with the latest version(Spire.Doc Pack(hot fix) Version:9.11.6). If the problem still exists after trying, to help us have further investigation, please provide your sample Word file and your test environment, such as OS info (E.g. Windows 7, 64-bit) and region setting (E.g. China, Chinese). You could attach them here or send them to us via email (support@e-iceblue.com). Thanks in advance.

Same issue still persists with the shared nuget package when the document is saved as a PDF. This issue is not seen when we try saving as a word document.

Hello,

Thank you for your sharing.
I tested your case and did reproduce your issue. After investigation, I found that the new engine method can solve this issue. The sample code is as follows.

Code: Select all

 < PackageReference Include = "Spire.Doc" Version = "9.11.6" />
 public async Task<Stream> GenerateInvoiceDoc(param)
 {
     document.LoadFromFile(localPath);
     //do something with the content
     ...
     // use the new engine method
     document.UseNewEngine = true;
     document.SaveToFile("test.pdf", FileFormat.PDF);
 }

Thank you for sharing the response. However with the UseNewEngine set as true, we have a new page introduced which says :
"Free version converting word documents to PDF files, you can only get the first 3 page of PDF file.
Upgrade to Commercial Edition of Spire.Doc <http://www.e-iceblue.com/Introduce/word-for-net-introduce.html>"

Hello,

Thank you for your feedback.
Kindly note that the new engine method is a new method in the commercial version of Spire.Doc. If you use the free version, the behavior you mentioned will appear. So please remove all the DLLs related to Free Spire.Doc in the project, and then install Spire.Doc Pack (hot fix) Version:9.11.6 from Nuget Manager.
