title: How to differentiate 2 IDs with simmilar letters
body: <pre><code>INSERT INTO `tablecity` (`City`, `Country`) VALUES ('Itajaí','Brazil');
  INSERT INTO `tablecity` (`City`, `Country`) VALUES ('itajai','Brazil');
  </code></pre>
  
  <p>Yea I know the 2 must be the same city. Let's for a while pretend that those are 2 completely different cities.</p>
  
  <p>Why do I get duplicate entries? The letters are different. How do I make mysql to treat the 2 entries differently?</p>
