Well, one solution could be to use something like this :

# strip away escape sequences
# hint: colorstrip() doesn't modify its argument, instead it returns the
result
#
function stresc() {
  perl -MTerm::ANSIColor=colorstrip -nle '
    $_ = colorstrip($_);
    s,\r,\n,g;
    s/\x00/<0x00>/g;
    s/\x1b\x28\x42//g;
    s/\x1b\x5b\x4b//g;
    print;
  '
}


This works fine here since a while
