title: RegEx check for Spanish Characters
body: <p>We currently have a regEx expression in one of our .net infragistics Text controls that allows for all English characters to be entered.</p>
  
  <p>The problem now is that we have a Spanish speaking user using the system and therefore they need to be able to enter the non-English Spanish alphabet characters into the textbox.</p>
  
  <p>How do I add the Spanish alphabet characters into our RegEx check expression?</p>
