title: Validation of a validation expression
body: <p>I am working with ASP.NET 3.5, VB.NET, and I am trying to validate some inputs through a regular expression.</p>
  
  <p>My expression is:</p>
  
  <pre>^[a-zA-Z'_''-''/'' ''\''@''&''.'',''ç''Ç''ö''Ö''I''ı''i''İ''ğ''Ğ''ş''Ş''ü''Ü'\s\d]{1,50}$</pre>
  
  <p>And it works for all the special characters I included except for the "<strong>-</strong>". It just doesn't work. I tried Internet Explorer and Firefox, same problem. How can it be fixed?</p>
