title: How to deal with Latin characters for password validation using Regex expression?
body: <p>I am writing code for password validation which should have one Uppercase, one lowercase, One number and One special character from a given set. I wrote regex expression for this. I don't know how to take care of Latin characters like "ÏÐÑÜÝÞßàáâ". whether these latin characters will count in UpperCase or Lowercase or special characters.</p>
