Acrobat Reader DC Open Error Dialogue - "An error exists on this page..."

Hi guys,

When I convert my HTML to PDF and try opening it in Acrobat Reader DC, an error dialogue shows, saying "An error exists on this page. Acrobat may not display the page correctly..." I've done a little bit of research and the potential problem is from the conversion of the HTML string. If there are inline characters "\n" this should be encoded using Converter.ToBase64String then decoded using Converter.FromBase64String, instead of Encoding.UTF8, etc.

Please let me know if anyone is able to change the source code for this and publish it to the next version.

Regards,

Adhy
