title: Split string in fixed length number
body: <p>I have a problem using <code>scan</code> with strings. My string is: (text variable)</p>
  
  <pre><code>"Nao ha nada novo porque somos preguicosos."
  </code></pre>
  
  <p>I use:</p>
  
  <pre><code>textdata = text.scan(/.{#{text.length - clearnum }}/)
  </code></pre>
  
  <p><code>textdata[0]</code> is:</p>
  
  <pre><code>"Nao ha nada novo porque somos preguicoso"
  </code></pre>
  
  <p>and <code>textdata[1]</code> is nothing. I need <code>textdata[1]</code> to be <code>"s."</code>. Does anyone have a solution?</p>
