Characters are represented using 16 bits (2 bytes) each. A string is a 1-d array of characters. Character codes are required to represent all of the required symbols in a human-readable language. Upper case, lower case letters, the space character. Special character codes are useful to have to express text formatting and to control input/output devices.
