Little off-topic note:

I'm always amazed when I see this spelling. I guess you don't actually have those letters on your keyboard, unless you use french a lot and have french keyboard layout installed. So it must be little complicated to write that word for you. I'm sorry, but it looks little snob to me. English doesn't keep original spelling of assimilated words except for this "naive" or "naivity". I suppose you wouldn't write "well, да" but rather "well, da". Or "canyon", not "cañón".
