[twitter-bootstrap-3] Bootstrap 3 Glyphicons are not working

In my case I was getting a 404 for glyphicons-halflings-regular.woff, and non visible glyphicons on mobile browsers.

Looks like there is some confusion about the MIME type for woff, more than one MIME type being accepted by different browsers, but the W3C says:

application/font-woff

Edit: After testing the following MIME type for woff works on all browsers currently:

application/x-font-woff

Edit: Latest version of Bootstrap at this time (3.3.5) uses .woff2 fonts with the same initial result as .woff, the W3C still defining the spec but at the moment the MIME type seems to be:

application/font-woff2
