-v Display non-printing characters so they are visible. Control
characters print as ‘^X’ for control-X; the delete character
(octal 0177) prints as ‘^?’. Non-ASCII characters (with the high
bit set) are printed as ‘M-’ (for meta) followed by the character
for the low 7 bits.
Backspace = back space = rubout = delete
