In Perl, I could do it this way:
$string =~ tr/\x00-\x1f\x80-\xff//d;
What that means is this:
remove the following characters from $string:
characters whose ASCII value is from \x00 (0) to \x1f (31)
characters whose ASCII value is from \x80 (128) to \xff (255)
This can be done, almost as painlessly, in Python.
