Incompatible character encodings error when I send arabic number to my ruby rack server

I have a simple rack based ruby server that I run using Thin, it looks something like : 

#encoding: utf-8

class Auth

  def initialize(app)
    @app = app
  end

  def call(env)
    @request = Rack::Request.new(env).params
    command = @request['command']

    begin
      command.tr!('٠١٢٣٤٥٦٧٨٩','0123456789')  
    rescue Exception => e
      $LOG.error e.to_s    
    end
  end
end

As you can see, it is supposed to translate numbers from arabic to english, anyways when I send param command "١" I'm getting this error : 

incompatible character encodings: ASCII-8BIT and UTF-8

command("١".force_encoding('UTF-8'))
