title: Regular expression to find a lowercase letter followed by an uppercase
body: <p>I have difficulty using Regular Expression (Grep) in TextWrangler to find occurrences of lowercase letter followed by uppercase. For example:</p>
  
  <p>This announcement <strong>meansStudents</strong> are welcome.</p>
  
  <p>In fact, I want to split the occurrence by adding a colon so that it becomes <strong>means: Students</strong></p>
  
  <p>I have tried: </p>
  
  <pre><code>[a-z][A-Z]
  </code></pre>
  
  <p>But this expression does not work in TextWrangler.</p>
  
  <p>*<strong><em>EDIT</strong>: here are the exact contexts in which the occurrences appear (I mean only with these font colors).</em>*</p>
  
  <pre><code>&lt;font color =#48B700&gt;  - Stột jlăm wẻ baOne hundred and three&lt;br&gt;&lt;/font&gt;
  
  &lt;font color =#C0C0C0&gt;     »» Qzống pguộc lyời ba yghìm fảy dyổiTo live a life full of vicissitudes, to live a life marked by ups and downs&lt;br&gt;&lt;/font&gt;
  
  "baOne" and "dyổiTo" must be "ba: One" and "dyổi: To" 
  </code></pre>
  
  <p>Could anyone help? Many thanks.</p>
