Hmm.. I always wonder about this, actually. I recently had to send a payment to a friend in yen, so she could get something for me in Japan, and their fees based on international transactions are incredibly... vexing to figure out x.x; I always do transfers direct from my bank account and usually for ebay or merchants, so usually I don't have to bother with the fees- but it took me about an hour to figure out what/whether there would be a charge or not and what it would be.
Paypal really just goes out of their way to make their fees as confusing as possible, I think :/
