I was writing a console application in SharePoint 2013 to fetch the content of PublishingPageContent in wiki page.
I had converted the page from Word document to Web page using SharePoint 2013 OOTB "Convert To" option in Wiki Site.
However , When i fetch the content of PublishingPageContent it returns unicode characters and unclosed html tags in SharePoint 2013 which is unexpected.
The same is working perfectly in SharePoint 2010. Not sure why this change happened in SharePoint 2013.
This is strange in SharePoint 2013 wiki site.
