I have a warning in Google for my font-face:
Resource interpreted as Font but transferred with MIME type application/octet-stream: \".../Content/Fonts/iconFo
If you run a server with nodeJS, this is a nice module to map your mime types
https://github.com/broofa/node-mime
var mime = require('mime');
mime.lookup('/path/to/file.txt'); // => 'text/plain'
mime.lookup('file.txt'); // => 'text/plain'
mime.lookup('.TXT'); // => 'text/plain'
mime.lookup('htm'); // => 'text/html'
mime.extension('text/html'); // => 'html'
mime.extension('application/octet-stream'); // => 'bin'
