Asset Pipeline Encoding Problems (UTF-8 Vs. ASCII-8BIT) With External Gem

I'm trying to create a gem that wraps d3.js, Source can be found at https://github.com/iblue/d3-rails So when I include this gem in my Gemfile gem 'd3-rails', :git => 'git://git

Solution 1:

Is the error from a WEBrick server or something else? Does rake assets:precompile work? (don't forget to clear the assets after)

If the latter fails, double check the value of your $LANG environment variables is UTF-8 (with env). If the rake task works but the app is failing then it could be the server env vars.
