title: jQuery: write html symbols in SVG tspan
body: <p>I'm trying to write HTML symbols (like <code>&amp;deg;</code>) in a TSPAN element with jQuery.
  In a simple SPAN it's easy:</p>
  
  <pre><code>$('#span_id').html('&amp;deg;');
  </code></pre>
  
  <p>With the TSPAN this way doesn't work, if I use</p>
  
  <pre><code>$('#tspan_id').html('&amp;deg;');
  </code></pre>
  
  <p>nothing is printed out.</p>
  
  <p>With </p>
  
  <pre><code>$('#tspan_id').text('&amp;deg;');
  </code></pre>
  
  <p><code>&amp;deg;</code> is printed  instead of <code>°</code> (obviously)</p>

  <p>How can I do?</p>
