The order of combining marks that appear in different parts of the
letter space is unimportant: thus, A, acute, dot below is the same
as A, dot below, acute.  However, A, acute, circumflex renders the
acute nearer to the A than the circumflex, and so is different
from A, circumflex, acute: inside-outward is the general rule
for all combining character that can interact.

The property called Canonical Combining Class is used to give a
preferred ordering to cases like A, dot below, acute (this one
is preferred).  All combining characters in the same area have the same
combining class: all base characters, and combining characters that
don't interact with others, have class 0.

Someone with a font editor could extract the Right Stuff from one of
the freely reusable fonts like Code2000.
