Is that a typo above?
I find count-words, not count-word.

in 24.1.1 I see:

  count-words-region is an interactive compiled Lisp function.

  It is bound to M-=.

  (count-words-region START END)

  Count the number of words in the region.
  If called interactively, print a message reporting the number of
  lines, words, and chars in the region.
  If called from Lisp, return the number of words between positions
  START and END.

Seems to mention characters.
