Box character being inserted when combining .doc sections

The attached project demonstrates a problem with Aspose Words where when combining multiple sections (from .doc files) some sections will have a box character inserted at the beginning of a section in the resulting output document.

Hi

Thanks for your request. I checked the output document produced by the application you have attached, and I cannot see any box characters at the beginning of document’s sections. Could you please make a screenshot and attach it here? I will check it as well and provide you more information.
Best regards.

The output.doc that is generated by the attached project has a box character that appears at the beginning of pages 2 and 3 for me in both Word 03 and 07. I’ve attached a screenshot from Word 03 and the generated document.

Hi

Thanks for your request. I cannot see any box characters on my side. I tried opening your document in MS Word 2007 and 2003. It seems for some reason MS Word on your side cannot properly display LineFeed character. Which version of MS Word do you use?
Best regards.
