Removing junk characters from text files?

[Henry Spencer]

I wrote:

	tr -cd '\n[:print:]'

Wups, one small snag with that:  tr may have its own ideas about just what
characters are printable.  To nail it down, if necessary:

	tr -cd '\n\040-\176'

That gets rid of everything except newlines and the printable ASCII
characters.  (\177, aka character 127, is not printable.)
