Actually I get what he is saying, '\n' is a char, but unsigned char
and signed char are different types from char, and they should be
distinct from char and displayed as integers, where char should be
displayed as a string.  I always have to remember to display my byte
arrays as hex as:
std::cout << std::hex << static_cast<int>(bytearray[i]) << ' ';

Way too freaking verbose when bytearray is an array of unsigned char's
(typedef'd as byte).
