Emoticons

An emoticon is a pictorial representation of a facial expression using punctuation marks, numbers and letters, usually written to express a person's feelings or mood.

There are different types of emoticons: 

Western style: 

Usually, emoticons have the eyes on the left, followed by nose and the mouth: :( , <3 , :-{ or :{D .

Japanese style: 

Users from Japan popularized a style of emoticons that can be understood without tilting one's head to the left: (^.^),  >.<, o_O, O.O.

Further variations of emoticons may be produced by using combining characters, e.g. ٩(͡๏̯͡๏)۶ and ᶘᵒᴥᵒᶅ.

Eastern style:

Eastern emoticons generally are not rotated, and may include non-Latin characters to allow for additional complexity: ｡◕‿◕｡ , (^▼^) , ~_~ , (-_-') .

Korean style: 

In South Korea, emoticons use Korean Hangul letters. There are countless number of emoticons that can be formed with such combinations of Korean jamo letters: ㅜ_ㅠ,  'ㅅ', ㅜㅇㅡ, -_^. 

There are multimedia varitions of emoticons too! 

A portmanteau of emotion and sound, an emotisound is a brief sound transmitted and played back during the viewing of a message, typically an IM message or e-mail message.
