rails encoding problem

I was trying to send an http request in my controller to get the content of the response and display it in a text field in the view, but sometimes i got a "redundant UTF-8 sequence" exception. Even if the exception was not raised, the chinese characters cannot be properly displayed.What should I do?

post your controller code...

my action code:   def get_content     @url = params[:url]     response = Net::HTTP.get_response(URI.parse(@url))     @content = response.body   end
