In the Mac Core Text font-backend driver I'm developing, these scripts
are laid out by the function `ctfont_shape' that is implemented using
the layout engine in Core Text framework instead of libm17n-flt.  But
I could not find any examples of the case that LGLYPH_ADJUSTMENT
becomes non-nil in etc/HELLO.  Could you possibly give some examples
where LGLYPH_ADJUSTMENT is essential so I can test such cases?
