I hope you like long lines.

Might I propose [\n\t\r -~]?

However, I suggest that any programs that cannot deal with characters
0-127 are broken and should be fixed.  Admittedly, outputing 27 to the
terminal raw could trigger a security hole in many terminals, and
several other terminals have problems with another character (I'm
vaguely thinking 17, but not sure.)

(The preceeding paragraph should not be taken as an alternate solution,
but one to combine with restricting characters to the above recommended
9, 10, 13, 32-126.)
