Hexdump will 'sanitise' the ASCII.
Although I think you'd want a 'no hex' flag to suppress the hex.
Probably more useful flags are ones to suppress the address column.
I've also used flags to enable (or disable) suppression of multiple
lines of zeros of constant bytes.
In that case you may want hexdump to return the flags for the
next call when a large buffer is being dumped in fragments.
