@kpumuk Can we get this updated and merged? I could provide tests for this as well.

The main idea was to remove HTML tags, which strip_tags does. I understand the problem with special chars, but the PR as it is now breaks the initial goal, allowing certain HTML tags to pass through. If you would update it to make sure no HTML tags pass through, and add specs - I don't see any reasons why it could not be merged.

And it breaks current specs suite :-)

We pass encode_special_chars: false to Loofah when doing strip_tags now.
