Comment (by toscho):

 It was at least possible to read and write text. I am not sure about the
 link tool.

 Currently, you have to know where the problem comes from to solve it. When
 the back-end was XHTML, you could find it with a validator. But no, in
 HTML 5, an `id` attribute [http://mathiasbynens.be/notes/html5-id-class
 with brackets (and other characters)] is valid.
