There is no way to avoid having to handle HTML safely. There's no point in trying to limit your exposure to that problem when the entire point of this standard is to ship around arbitrary HTML for interfaces to display. Once you've solved the hard problem of displaying the body safely, displaying the title is trivial. Making the title pure text does nothing useful. JSONFeed display mechanisms that are going to get this wrong are going to do things like leave injections in the date fields anyhow.
