title: How to replace Unicode characters with ASCII
body: <p>I have the following command to replace Unicode characters with ASCII ones.</p>
  
  <pre><code>sed -i 's/Ã/A/g'
  </code></pre>
  
  <p>The problem is <code>Ã</code> isn't recognized by the sed command in my Unix environment so I'd assume you replace it with its hexadecimal value. What would the syntax look like if I were to use <code>C3</code> instead?</p>
  
  <p>I'm using this command as a template for other characters i'd like to replace with blank spaces such as:</p>
  
  <p>sed -i 's/©/ /g'</p>
