FWIW, I've got this in my ~/.emacs:

(add-hook 'text-mode-hook
           (defun text-mode-punctuation-syntax ()
             ;; Change non-letter characters from word syntax to 
punctuation:
             (modify-syntax-entry ?\240 ".") ; NO-BREAK SPACE
             (modify-syntax-entry ?' ".")))  ; APOSTROPHE
