Emoji are pictograms used (typically) on cell phones, originating with the NTT DotCoMo. See http://en.wikipedia.org/wiki/Emoji.
A table of cut and pastable emoji is available at http://getemoji.com
Emoji will only show on web pages where the underlying unicode pictograms are supported, e.g. on Apple tablets and phones, and some Android devices.
