+All frequently used characters have 2-byte codes (4 hex digits). Letters in most European languages, numbers, and the basic CJK ideograph set (from Chinese, Japanese, and Korean writing systems), have a 2-byte representation.
 
 Initially, JavaScript was based on UTF-16 encoding that only allowed 2 bytes per character. But 2 bytes only allow 65536 combinations and that's not enough for every possible symbol of Unicode.

 That's because surrogate pairs did not exist at the time when JavaScript was created, and thus are not correctly processed by the language!
