If ZWNJ is WITHIN a grapheme cluster (i.e. not at the edges
of the cluster), the m17n lib does not return ZWNJ glyph.

If Unicode does not have a rule of ZWNJ handing, to delete ZWNJ, how a
user know which to type; C-d or BS? And while doing cut&paste
repeatedly, are there any chance of having the second and third lines of
the attached file? They have two and three consecutive ZWNJ. How does
a user notice such a (perhaps incorrect) situation?
