$ in identifiers?!?

[Leandro Oliveira]

is there any problem with using $ in identifiers??? I know jls states that _ and $ can be used but somebody (not here, in the forum) said it is problematic!! is it true???

shouldn't be....
this code works fine and dandy:

public class Identifiers
{
   public static void main( String [] args )
   {
      int $Dollar = 4;
      int �Cent = 5;
      int �Pound = 6;
      int �Yen = 7;
      System.out.println(" $ = " + $Dollar);
      System.out.println(" � = " + �Cent);
      System.out.println(" � = " + �Pound);
      System.out.println(" � = " + �Yen);
   }
}
