Unity JavaScript for Convert.ToInt(Char) ?

Is there a way to convert a letter in a string to it’s unicode value in Unity’s JavaScript ?

e.g.

var uniString : int = Convert.ToInt("T");	
Debug.Log( uniString.ToString() );

I think this would do it:

   var a = (int)("Hello"[0]);

EDIT Ugh that’s c# - didn’t read the question

   var a : int = ("Hello"[0]);

If you want to actually use System.Convert, then the syntax is

var uniString : int = System.Convert.ToInt32("T"[0]);
