The lastest wordpress update which is WordPress 4.2 codenamed “Powell” includes a new feature to add emoji essentially anywhere (including in your URL slug). However this feature also requires a recent browser which supports emoji in url to view the page.
The latest wordpress update also adds support for a number of new embed types, such as Tumblr and Kickstarter, which are formatted automatically for inclusion in your posts. Just paste links from Tumblr.com and Kickstarter and watch them magically appear right in the editor.
