Emoticons have been used as communication for years and years, starting with the simple smileys : ) and : ( moving to slight variations to show different moods, such as : ‘( : P and : D
Before Nicolas Loufrani adapted text emoticons to become the world’s first graphical emoticons, and making thousands more every day, Korean and Japanese people had started experimenting with different keyboard symbols to create different emoticons. For Koreans, something upturned or with bubbles indicate positive feelings; negative emotions are shown through dashes, dots, semi-colons, and down-turned symbols; asterisks illustrate blushing or cuteness, and repeated symbols show emphasis or frequency. 
Quite often, these emoticons indicate more than facial expressions, symbolising feelings such as excitement, by showing the act of throwing hands up in the air (^0^)/ in a literal, text format. As a language based on characters, adapted from the Chinese script called hanja, it’s no wonder that emoticons can be used in communication interchangeably with letter symbols.
