    # Our own, personal, icon helper. This is relying on
    # `font-awesome-rails` to include all the assets for font-awesome
    # to work. It's mimicking the API of the `font-awesome-sass` gem,
    # which uses font-awesome version 5 but we can't use it because of
    # a sass naming clash.
    #
    # So in the ideal world, rails_admin drops the font-awesome-rails
    # dependency and we migrate to font-awesome-sass (if we do: search
    # for 'fa5' in the codebase to fix some icons in the JS).
    #
    # At the moment we can't use them both, because the line:
    #      @import "font-awesome"
    #
    # Will import the stylesheet of the `font-awesome-rails` gem
    # instead of the `font-awesome-sass` gem, so we're back to using
    # `font-awesome` version 4.
    #
    # That's why this helper is there, it uses the API of
    # `font-awesome-sass` but transforms it into version 4 of
    # `font-awesome`.
    text, html_options = nil, text if text.is_a?(Hash)

    # Font awesome 4 only has 'fa', so while the views pretend to use version 5,
    # we're just using version 4.
