It would also be trivial to write a program to update the dictionaries to include the flipped / reversed / other silly unicode trick version of everything already in the dictionary. I wouldn't assume that this would help against dictionary attacks for long, if at all now considering that people have been doing stuff like this pretty much since unicode got "mainstream" status.
