Problem starting heroku: get Invalid char '\024' error in log

I am working through the ruby on rails tutorial. I have all of the test passing and deployed to git hub.

When I deployed to Heroku and opened the online application it tells me something went wrong.

I looked at the log files and this is what was written:

ActionView::Template::Error (compile error
  /app/app/views/pages/home.html.erb:10: Invalid char \024' in expression):
            <%= render "shared/feed" %>
            </td>
            <td class="sidebar round">
            <%= render "shared/user_info" %>
        </tr>
     </table>
     <开发者_运维百科% else %>     
   app/views/pages/home.html.erb:23:in `compile'

any ideas how to fix this error?

this may sound silly but after you deploy the app did ran heroku rake db:migrate also make sure you close that if statement with <% end %>

make sure your code has no "special" encoded characters (ex: from copy and paste...)...

Apparently I had some "null" values instead of null in my database which was causing the problem. Once I cleared those out everything worked perfectly.
