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: test_multibyte_queries.rb
    path of file: ./repos/peddler/test/integration/internals
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'integr
    
  def test_posting_multibyte_queries_properly
    ret = clients.map do |client|
      res = client.list_matching_products(client.marketplace.id, 'félix guattari machinic eros')
      res.body.force_encoding 'UTF-8' if defined? Ox # Ox workaround
      res.parse
    end
    assert_includes ret.map(&:to_s).join, 'Félix'
  end
