title: Regular expressions and multiple writing systems
body: <p>Types of writing systems:</p>
  
  <ul>
  <li>Alphabet </li>
  <li>Abjad </li>
  <li>Abugida </li>
  <li>Syllabary</li>
  <li>Logography</li>
  </ul>
  
  <p>In regular expressions we need to tell which "chars" we want to validate:</p>
  
  <p>We use something like this a-zA-Z0-9 to say that we accept all the alphanumeric.</p>
  
  <p>How can we make regular expressions that validate other writing systems non-alphanumerics?
  (how can I make a regular expression that will validate chinese, or indian, or greek or russian, or someother?</p>
  
  <p>UPDATE:</p>
  
  <p>Using ASP.NET regex engine.</p>
  
  <p>If you don't mind, could you provide me some examples?</p>
  
  <p>Thanks</p>
