You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: base.rb
    path of file: ./repos/mushroom-observer/app/classes/report
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Report
  # bas
    
    def body
      case encoding
      when "UTF-8"
        render
      when "ASCII"
        render.to_ascii
      else
        render.iconv(encoding) # This caused problems with UTF-16 encoding.
      end
