Yes, true, a 100% safe sanitizer is a dream at least for older browsers versions. Of course you can choose a different approach using a different markup language. My approach to this problem is to preserve as much html you can. The older version was laking of a css black list that has been addded. By default this sanitize encode unknown chars, and is easy to add white or black elements
