 * of the readUnsignedShort  method . This integer value is called the UTF length and specifies the number of
 * additional bytes to be read. These bytes are then converted to characters by considering them in groups. The
 * length of each group is computed from the value of the first byte of the group. The byte following a group, if
 * any, is the first byte of the next group.
