The script was written to be able to deal with binary files, but it had a bug corrupting some data: e.g. a byte sequence 0x1 0x37 was printed as "\17" (0x1 = escaped as "\1", and 0x37 = kept as literal "7"), which would be interpreted as single character 0xF. Always pad octal literals to length 3, which makes the escape sequences unambiguous.
