title: string.chars.length vs string.length
body: <p>I'm migrating from Rails 2.1.2 to 2.3.5 and one of the items that doesn't work anymore is </p>
  
  <pre><code>"string".chars.length
  </code></pre>
  
  <p>I used the console to discover that "string".chars is a ActiveSupport method in 2.1.2 and an Enumerable in 2.3.5</p>
  
  <p>So, in completing this migration, I was wondering what the difference is in using </p>
  
  <pre><code>"string".chars.length
  </code></pre>
  
  <p>vs</p>
  
  <pre><code>"string".length
  </code></pre>
  
  <p>Will they return the same thing? They appear to, I just wanted to know if you know the difference so I can learn?</p>
  
  <p>Thanks</p>
