title: Vagrant Windows-1251 encoding error
body: <p>I got the next error with vagrant when trying to use "vagrant up" command:</p>
  
  <pre><code>Bringing machine 'default' up with 'virtualbox' provider...
  ==&gt; default: Importing base box 'precise32'...
  C:/HashiCorp/Vagrant/embedded/gems/gems/childprocess-0.5.3/lib/childprocess/wind
  ows/process_builder.rb:43:in `join': incompatible character encodings: Windows-1
  251 and UTF-8 (Encoding::CompatibilityError)
  </code></pre>
  
  <p>I have Windows 8.1, and I used "chcp 1251" command before, because it was the same error with "ibm866" encoding.</p>
  
  <p>Thanks!</p>
