Question

I’ve started getting the following error in one of my views for some reason, I don’t get it in development, but only in production.

Here is a snippet of the backtrace, any ideas?

ActionView::Template::Error (code converter not found (UTF-8 to UTF-16)):
    19:         [title, summary.gsub(/^/, "  "), nil].join("\n\n")
    20:       end
    21:     end.join
    22:     sections = sections.force_encoding('UTF-8').encode('UTF-16', :invalid => :replace).encode('UTF-8') if sections.respond_to?(:force_encoding)
    23: %>
    24: 
    25: <%= raw sections %>

After some fiddling, I traced the problem to included javascrips in my view, based on conditionals, which had to manually be listed in rails configuration in order to be put through the asset pipeline.

The relevant info from Rails Guides is:

If you have other manifests or individual stylesheets and JavaScript
files to include, you can add them to the precompile array:

config.assets.precompile += [‘admin.js’, ‘admin.css’, ‘swfObject.js’]

in production.rb

# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
# config.assets.precompile += %w( search.js )
