title: json encoding € symbol
body: <p>I have a php page generating json extracting values from a mysql table.
  Everything is fine except where I have values containing euro symbol (like "€ 20,00") the euro symbol show up in my json as \u20ac... </p>
  
  <p>Like this:</p>
  
  <pre><code>[
    {
      "id": "535",
      "Name": "Pluto",
      "fare": "\u20ac 20,00"
    }
  ]
  </code></pre>
  
  <p>In the page evaluating this json it appears as "€ 20,00", so this is fine, but I really would like it to appear the same also in the json string itself.</p>
  
  <p>Any hint?</p>
