When I run `rake db:seed` in my `Rails` app, I&#39;m getting this error:

&gt; invalid byte sequence in US-ASCII (Argument Error)

I just added `science_majors` and down to my seed file, and now when I run `rake db:seed` it gives me this error:

&gt; invalid byte sequence error

Why is this, and how can I fix it?

I left out all the other colleges. I have 200 schools so far, but Pitt is the only one with comprehensive data so far.  The rest just have basic data, like Harvard.  I also left out some of the data for Pitt for the sake of brevity, but let me know if you&#39;d like me to include the rest.

Edit: I tried taking out the `*`&#39;s in `science_majors` on down and then running `rake db:seed`, but that didn&#39;t change anything.
