I'm wondering how long it might take a > less Emacs-savy user to learn that he can `C-x ='. FWIW, it took me, your "less Emacs-savy user", about ten years to discover `C-x ='. (I found M-x describe-char only slightly sooner.) Before that, if I was suspicious about characters being displayed I'd open the file in a hex editor. (It took me until today to discover Hexl Mode in Emacs!) While I'm here, I may as well say that I'm not happy with Emacs changing / misdisplaying characters on me (/ for me) without some sort of visual indication or message, and it would be nice to have a user option to tell Emacs not to make such substitutions. An empty box (or one of those boxes with the number of the codepoint in them) would be fine for me if none of my available fonts can display the character.
