Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters.
, Started with C, now in love with Java. 2 Bytes = 16 Bits = 2^16 different characters are supported. Therefore, characters from most of the languages will fit inside 2 Bytes. However, there certain languages or characters (Esp from Chinese, Japanese languages) which require more than 2 bytes to store the data.
