Ruby on Rails Bootstrap Glyphicons not working

Question

I have added bootstrap to my site. Here is the structure I am using. (I cannot whatsoever remove the bootstrap.css file since it I modified it to my liking).

Answer 1

According to Bootstrap 3 Glyphicons are not working, there's a bug with the Bootstrap customizer that messes up the glyphicon fonts. I had the same issue, but I was able to fix it by downloading the entirety of bootstrap from http://getbootstrap.com/, and then copying the font files to the correct location.
