'paper plane' icon doesn't render

[ldanielswakman]

The icon with the title 'paper plane', or html code 🔿 does not display at all in this github build of Entypo. It occurs when using the web font, occurs in 3 browsers (Chrome, Firefox and Safari / all Mac).

The DOM seems to respect the space the icon would take, but the character is invisible. Perhaps this is an issue with compiling and can be easily solved?

I prefer this build over the download from entypo.com because the default character height is a a lot bigger, so I don't have to mess around with font-sizes as much.
