Are you going to type that string into your terminal manually, or are you just copy/pasting that line from a web page, still leaving yourself open to this issue? I find it hard to believe anyone will be reading that line on a web page, then typing it out correctly in their own terminal instead of just saying, "ok that line looks fine copy paste"
