This validates my LaTeX usage, but honestly, can’t you only detect it if I’m using Computer Modern? I am, precisely because of people like you, but I don’t think you could tell a XeTeX-built resume with a Unicode font from one done in Word. And conversely a Word user could simply download CM Unicode and reap the LaTeX bonus points, no? :)

I include \latex in my resume under "skills" for this reason. But I agree, it's hard to tell.
