title: C# How to replace an accent insensitive string with regex?
body: <p>I'd like to perform an accent-insensitive replace in a string. I want 'client' to match 'cliënt' and vice versa.</p>
  
  <p>My code looks like this:</p>
  
  <pre><code>Regex reg = new Regex("client");
  string result = reg.Replace("here goes the content with client and cliënt", "replacementWith");
  </code></pre>
  
  <p>So, how do I make sure that 'client' matches 'client' and 'cliënt' and vice versa?</p>
