Apart from syntax-class, 2 chars form a word boundary, if they do
not share a common character category. You need to do something
like this:

(let ((latin ?l)
      (other
       (aref (category-set-mnemonics
              (char-category-set ?’)) 0)))
  (add-to-list 'word-combining-categories
               (cons latin other))
  (add-to-list 'word-combining-categories
               (cons other latin)))


For the whole story read

(describe-variable 'word-combining-categories)

and maybe

(info "(elisp)Categories")

.
