What’s Emoji? ✈
Emoji is the Japanese term for the picture characters.
You could think of this as the emoticon font. That means they can be used in electronic messages and webpages. There is a twist, this font is only on some devices. Supported in Apples OS X 10.7 Lion, Windows 8, and on most mobile devices now including the iPhone.

With every page download come all the assets tied to that page: Images, fonts, videos, embedded content. If the images or fonts are on the device, cached, stored in local-storage, or native to the device we can take advantage of some of them. This means that if you have access to Emoji, and the subject matter calls for it then you have a short cut around downloading images.
