Hello ajithraj, your:

var c = "\001";

is returning "" character.

I'm not sure if "" is meant to be treated as a new-line character, nor if it is being treated as such. But I expect that, if this code is being passed as content of a html string - it will be dropped somewhere between passes.

I guess, that's because "innerHTML" interface on IEs has a correct meaning: a HTML code! While others might treat it as if it was "innerText" (that is: a plain text string). And because of that, your code might suffer from content normalization on its trip back.
