If you encounter a problem where fonts don’t work on production when using Bourbon CSS toolset, you need to replace the font declaration from:
@include font-face("greatfont", "greatfont", $asset-pipeline: true)
This will use asset pipeline fingerprinted URL in the font declaration and should work on all environments.
P.S. With rails 4.0+ you only need to put font files in app/assets/fonts and they will be fingerprinted and zipped.
