Twitter bootstrap glyphicons do not appear in release mode 404

Here’s how I solved it — I’m using MVC5 and Bootstrap 3.1.1.

I have my files organized in the project like this:

/Content/Bootstrap/bootstrap.css
                   bootstrap.min.css
/Content/fonts/glyphicons-halflings-regular.eot
               glyphicons-halflings-regular.svg
               glyphicons-halflings-regular.ttf
               glyphicons-halflings-regular.woff

Then I added another level to my virtual path in the bundle config

bundles.Add(new StyleBundle("~/Content/site/css").Include(
    "~/Content/bootstrap/bootstrap.css",
    "~/Content/styles/site.css"
));

Previously I had used ~/Content/css

And in the view…

@Styles.Render("~/Content/site/css")

This worked but I still got a 404 on one of the fonts… so I added Giles’ solution.
