INVALID MULTIBYTE CHAR (US-ASCII)

I was playing with Couchbase and plain Ruby in my Terminal. Then I got the error message:invalid multibyte char (US-ASCII)or Message from application: /www/pro_edgudri_lv/app/models/plans_modification.rb:7: invalid multibyte char (US-ASCII)/www/pro_edgudri_lv/app/models/plans_modification.rb:7: invalid multibyte char (US-ASCII)/www/pro_edgudri_lv/app/models/plans_modification.rb:7: syntax error, unexpected $end, expecting keyword_end..._change, :message => "nevar būt tukšs"...                               ^ (SyntaxError)

If you got this error, you know that this is a result of having special chars. To fix this, you have to add a ‘magic comment’ in the script.


Here is a step-by-step instruction how to solve this problem:
1. Open your file
2. go to the VERY FIRST line of your code
3. write the following at the top of your file


#!/bin/env ruby
# encoding: utf-8



Example :- payment_controller.rb:-
# encoding: utf-8
class PaymentsController < ApplicationController


end
