title: validate string - only specific language characters
body: <p>Is there a way to check if a string contains characters of a given language only? (for example Japanese, Hebrew, Arabic) </p>
  
  <p>I'm wondering if there is a way implementing this kind of validation  in Javascript\Jquery and in c#?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I'm not willing to check if the string contains valid words of a specific language dictionary. I'd like to validate that all characters belong to that language.</p>
