Yeah that is how I understood the specification.

Oh nevermind me. Saving the page and using a hex editor I see that it
still is there. Sorry I was inspecting the DOM and the control
characters are invisible characters (early in the morning and my brain
is not functioning correctly).

So section '3.2.5.1.5 Phrasing content' is only referring to
conforming documents when it mentions that text nodes and attribute
values should not include control characters other than space
characters?
