My guess is probably not. Those characters are OS specific (\t is tab in Windows, but I'm not sure what represents tab in UNIX). As
Java tries to be "OS independent," I doubt you'll find anything that readily converts a char into something of that form. I'm guessing that, if you want to accomplish this, you're going to have to "roll your own" in one way or another.
Perhaps someone else has an idea, but that would be my guess.
