title: backslash in Yaml string
body: <p>So I'm using yaml for some configuration files and py yaml to parse it.
  For one field I have something like:</p>
  
  <pre><code>host: HOSTNAME\SERVER,5858
  </code></pre>
  
  <p>But when it gets parsed here what I get:</p>
  
  <pre><code>{
  "host": "HOSTNAME\\SERVER,5858"
  }
  </code></pre>
  
  <p>With 2 backslashes. I tried every combination of single quotes, double quotes, etc.
  What's the best way to parse it correctly ?
  Thanks</p>
