The result is different when using version 6.7 but still doesn't produce the expected result.

Here's an example where I am using an HTML string containing Microsoft Office tags:

and here's the result after cleaning it up with CuteEditor 6.7 (notice the HTML tag is missing, the entire HEAD section is missing and even the BODY tag is missing):

To be clear, I am simply trying to clean my HTML with the following line of C# code:

var cleanHtml = EditorUtility.CleanUpMicrosoftWordHTML(originalHtml); 

I will email the full HTML I use for my testing to support@cutesoft.net
