After successfully testing my “alpha” Rails 3 app in my local dev environment, I pushed it up to Heroku (Cedar) for live testing. The push was successful, but the app crashes upon startup with the following errors:

: => Booting WEBrick
: => Ctrl-C to shutdown server  
: /app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:251:in `require':   /app/app/controllers/dives_controller.rb:50: invalid multibyte char (US-ASCII) (SyntaxError)
: /app/app/controllers/dives_controller.rb:50: syntax error, unexpected $end
: Exiting

I have checked for unexpected characters and missing end statements, but can not seem to find any. I am not using any multilingual characters (to my knowledge).

Here are a few of my files including: Gemfile, Gemfile.lock, database.yml, dives_controller.rb

Could this possibly have something to do with using postgres and not specifiying it in my database.yml correctly?

    If you look at lines 50 and 51 of dives_controller.rb, you will notice some weird white-space sort of characters appearing before (they are highlighted in the github output). I have a feeling those are the characters that are causing the problem.

    They may have cropped up by pressing some random keys on your keyboard by mistake. Just remove them and replace them with a space.
