Assuming that you are on a *nix box you can open the file in ex and strip it
example:
I want to take all the ^M's out of a file.
root - local#ex somefile.ext
1,$s/.^M//g[enter]
w [enter]
of course you have to replace ^M with that crazy acii character. try cutting
and pasting if you cant

That's not at all how tr/// works. tr/// ALREADY is a character class
operator,
along those lines if you just want to
get rid of non-printable characters.

Someone out there may have a better answer, but this one seems tougher than

character. I suppose one way to go would be to create a character class
with all of the characters that you want to allow. Something like the
