If you use an iPhone, iPad or iPod Touch, you've undoubtedly seen at least one emojicon ("emoji" + "icon") come your way, if not many, many more.

Twitter and other social networks have made it necessary to almost rely on these special characters. Not necessarily a bad thing. It's just what it is.
Did you know that these emojicons aren't just limited to iOS devices? You can also generate the icons on your Mac. It's simple: when your cursor in the right place for insertion, go to Edit | Special Characters... from the menu. Locate the emojicon you want to insert (after browsing the categories), then double-click the icon to insert.
