Didn't bother to read the rest of your message, so apologies
if my guess is wrong.  My guess is that you are wondering
why a number (in this case 8) is shown that way.

If so, that's how Emacs shows a character interactively:
in decimal (8), octal (#o10), hexadecimal (#x8), and as a
character (?\C-h).  (In Emacs Lisp, a character is an
integer.)

So:

(setq foo ?\C-h) ; 8
M-: foo RET ; evaluate foo and print the value
8 (#o10, #x8, ?\C-h)

Same thing for (setq foo 8).
