How do I reverse text in Word 2007?

I don't want a mirror image to make an iron-on decal, I actually want to reverse the order of the letters, but do it letter-for-letter, including spaces and punctuation. I tried recording a simple macro, but all it did was to move the text to the end of the page in the same sequence. For example,

"?efiL fo gninaem eht si tahW" instead of "What if the meaning of Life?"
