Error while saving document


We have a problem while saving a file as HTML. I have minimized the contents of the file, but I cannot figure out what is causing the problem.

The anomaly was encountered on Aspose Word version 20.9

Here is the file and the error (2.6 MB) (2.61 MB)


We have converted the document to HTML using Aspose.Words 20.9 and have not faced the shared exception.

Please create a standalone console application ( source code without compilation errors ) that helps us to reproduce your problem on our end and attach it here for testing. We will investigate the issue and provide you more information on it.


Here are all the elements to reproduce this exception.

In the zip file :

  • the original file ==> OriginalDocument.docx
  • the code to reproduce ==> csharpCode.cs
  • a screenshot of the error ==> Screenshot.png
  • the html file and its folder ==> (outputDocument.html + _OriginalDocument_files)

The problem seems to be with the fonts.

Thanks. (4.5 MB)
