What is the length of a Unicode character? Correct Answer 16 bits

Unicode defines code points that can be stored in many different ways (UCS - 2, UTF - 8, UTF - 7, etc.). Encodings vary in simplicity and efficiency. Unicode has more than 65,535 (16 bits) worth of characters. Encodings can specify more characters, but the first 65535 cover most of the common languages.
