      Null-terminated byte strings

      A null-terminated byte string (NTBS) is a possibly empty sequence of nonzero bytes followed by a byte with value zero (the terminating null character). Each byte in a byte string encodes one character of some character set. For example, the character array{'\x63','\x61','\x74','\0'} is an NTBS holding the string"cat" in ASCII encoding.
