Hi @Aqualon, I took `"foo" "bar"` example from https://github.com/rspec/rspec-core/blob/34c2c750c48cf880b7194e3e295236afd92c0ca8/lib/rspec/core/configuration.rb#L147-L151, also see http://thepugautomatic.com/2015/01/backslashy-ruby/#comment-1780720281. ## Maybe this just a bad naming, do you have better name for [current example](https://github.com/JuanitoFatas/fast-ruby/blob/master/code/string/concatenation.rb)? Or add explanatory...

Or maybe we setup travis CI to run all versions for us? And README put benchamark result in 2.2 as an idea. If people are curious, check out results on...

I got this same error trace when redis is not installed / stopped. Start the redis fixed it (`brew services start redis`).

I can reproduce with Ruby 2.1.9: ``` irb(main):001:0> RUBY_VERSION => "2.1.9" irb(main):002:0> require 'yaml'; h = {name: '李'}; YAML.dump(h, File.new('out.yml', 'w:utf-8')) Encoding::UndefinedConversionError: "\xE6" from ASCII-8BIT to UTF-8 from /Users/Juan/.rubies/ruby-2.1.9/lib/ruby/2.1.0/psych/visitors/emitter.rb:27:in `write'...

Also `#`: ``` irb(main):001:0> Encoding.default_external => # irb(main):002:0> Encoding.default_internal => nil irb(main):003:0> RUBY_VERSION => "2.2.5" ``` for 2.1.9: ``` irb(main):001:0> Encoding.default_external => # irb(main):002:0> Encoding.default_internal => nil irb(main):003:0> RUBY_VERSION =>...

I tried to write a test: ``` ruby def test_dump_chinese_string_to_file Tempfile.create(['utf8', 'yml'], :encoding => 'UTF-8') do |t| h = {'one' => '李'} Psych.dump(h, t) t.close assert_equal h, Psych.load_file(t.path) end end...
