Where can I find an explained list of emoji (emoticons) used in iOS? Where can I find an explained list of  emoji (emoticons) used in iOS for use on Mac OS X?

Some of them are not quite clear and I would like to see their base meaning (I know that you are free to use them, still as the glyphs they should have an Unicode name).
First, in System Preferences, under the Keyboard tab of the Keyboard Preference Pane, be sure Show Keyboard and Character Viewers in menu bar is checked.


Then, from the Keyboard menu in the menu bar, select Show Character Viewer. In the Character viewer pane, select Emoji. When you select an Emoji, on the right side of the pane, you get a large graphic of the Emoji and a text explanation of the shape.
