      Description

      I used below code to save a excel file into Mongo but unfortunately I got the encoding error:

      require 'mongo'
      MONGODB_URL = 'mongodb://localhost:27017/'
      DEFAULT_DATABASE = 'game_of_threats_development'

      @db = nil
      @grid = nil

      begin
      @db ||= Mongo::Client.new(MONGODB_URL, :database => DEFAULT_DATABASE).database
      rescue Errno::ECONNRESET => e
      puts e.backtrace
      end

      data = File.open 'test.xls'
      grid_file = Mongo::Grid::File.new(data.read, :filename => 'test.xls')
      result = @db.fs.insert_one(grid_file)

      The error trace I got are:
