How Can i use Regex.Replace with Non-English "ARABIC Strings

Question

Hey Folks!

 

I am having a problem using Regular Expression in Non-English (URDU) string. I want to use

"Regex.Replace" with Urdu Strings to remove Special Characters but when I pass Urdu String to "Regex.Replace" it is removing entire urdu as considering it "NON-ENGLISH/INTEGRAL" value.

 

string name = Regex.Replace("Urdu ???? Here", @"[^0-9a-zA-Z]+" ," ");

 

Any suggestion?
