We say it near enough to the french original. And the differences in spelling actually make reading easier. Trust me I'm a linguistician. American spelling is just an excuse to cheat at Scrabble. I mean what is the point in changing plough to plow if you are going to leave snow as snow?
As one of SpM's signatures demonstrated, I glory in a language that has seven different ways to pronounce wourds ending in -ough (or is it 8?). If you want a ruthlessly logical language you end up with German which is pronounced as it is written but has 16 different ways to say "the" and the word for insectiside is 25 letters long.
