While working on some text, I ran into a problem with this.

In character sets, backslash isn't special at the moment. With any such
syntax it becomes special. If you're going to have \u, then you might as
well allow \\, \], \-, and so on, to have the "I literally mean the second
character" meaning in character sets.

Is this acceptable ?
