Search the forums, this has been requested and discussed a few times already. Though I'm not going to do the search for you as I personally find such inpersonations and tools to do it very lame... sorry...
All I can say is that copying the font is very hard todo and will even not always work in a decent way anyways as you wont always have the same font installed...
And on top of that, such scripts to do this will also quite often break other (much more usefull) scripts...
