When you have the "HTML encoded Unicode" option selected on the "Settings" page, the rewritten article output will look very odd as plain text. However, it will look normal and be 100% human readable in a web browser. Certain characters of unimportant words (such as 'and', 'the', etc) are replaced with HTML representations of look-alike characters. This list of words can be viewed and modified on the "Settings" page too.
This makes the article look perfectly normal to a human, yet the content appears to be extremely unique to bots, crawlers, websites, and unique content checkers. All of the important keywords are left unmodified, so you still get the benefit of having those keywords in the unique article.
