In all fairness, what Ashwin Kumar has done *is* a workaround since until the UTC meets next month there is no possibility of putting the INDIAN RUPEE SIGN in any place in a font apart from the Private Use Area or (as he has done) in ASCII.
It would be a bad thing for this to get put into real data, but in order to allow printing, it *is* a workaround.
