Realized this evening where Mr. Yidong may be looking to -> grapheme-clusters.

Now that the underlying Emacs encoding is "..to Unicode and Beyond"
this would seem a likely approach esp. coupled with the users
language-environment settings.

Fancy that...

(defun my-grapheme-fuzz-factor-pref ()
  (if (and (member
	    (cdr (assoc 'major-mode (buffer-local-variables)))
	    '(language-o-choice-mode
	      language-o-plenty-mode
	      emacs-rdf-graph-navigator-mode))
	   (and (assoc 'syntax-table text-property-default-nonsticky)
	   (cdr (assoc 'syntax-table text-property-default-nonsticky))))
  (setq right-most-grapheme-avoidance 3)))

  (set (make-local-variable 'grapheme-wrap-fuzz-factor) nil)))

  (add-hook 'buffer-grapheme-wrap-fuzziness-hook 'my-grapheme-fuzz-factor-pref)

Or, for the bidi bound - test for a front-skicky instead in
`my-grapheme-fuzz-factor-pref' and

  (setq left-most-grapheme-avoidance 3)  instead :)
