title: Greek characters, Regular Expressions, and C#
body: <p>I'm building a CMS for a scientific journal and that uses a lot of Greek characters.  I need to validate a field to include a specific character set and Greek characters.  Here's what I have now:</p>
  
  <pre><code>[^a-zA-Z0-9-()/\s]
  </code></pre>
  
  <p>How do I get this to include Greek characters in addition to alphanumeric, '(', ')', '-', and '_'?</p>
  
  <p>I'm using C#, by the way.</p>
