Emphasis characters are now hard-coded. You cannot change them, though,
you can change how each back-end interprets them.

We are solidifying Org syntax for parsing purposes. Allowing variable
markup is asking for trouble. The plan is to make `org-emphasis-alist'
a defconst.

On the other hand, you may be able to parse custom markup with the help
of a filter:

#+begin_src emacs-lisp
(defun my-special-markup (text backend info)
  (when (and (org-export-derived-backend-p backend 'html)
             (string-match "\\([        ('\"{]\\|^\\)\\(\\([?!#]\\)\\([^        
,\"']\\)\\3\\)\\([-     .,:!?;'\")}\\]\\|$\\)"
    (format (cond ((equal (match-string 3 text) "?")
                   "<span class=\"org-question\">%s</span>")
                  ((equal (match-string 3 text) "#") "<!--%s-->")
                  (t "<span class=\"org-exclamation\">%s</span>"))
            (match-string 4 text))))
(add-to-list 'org-export-filter-plain-text-functions 'my-special-markup)
