This should show non-printable characters in vi.
Actually, with most versions of unix, ":set list" only affects white space. It causes tabs to show up as ^I and newlines to be marked with $.

The real problem is that some bytes could have values in the range of 128 to 255 and you may not have an 8 bit data path to your terminal. Depending on the stty settings, the MSB may be a parity bit rather than a data bit. Also not all terminals will display something for non-ascii characters. And a final problem is that, I think, vi balks at attempting to display nulls, although it will count them and display a count at startup time.
