``unfold turns a character, say =C3=AB into the set of
characters that can be folded to the same base
character.  so
       ; unfold =C3=AB
       [e=C3=A8=C3=A9=C3=AA=C3=AB=C4=93=C4=95=C4=97=C4=99=C4=9B=C8=85=C8=87=
=C8=A9=E1=B8=95=E1=B8=97=E1=B8=99=E1=B8=9B=E1=B8=9D=E1=BA=B9=E1=BA=BB=E1=BA=
=BD=E1=BA=BF=E1=BB=81=E1=BB=83=E1=BB=85=E1=BB=87]''

To me, that sounds like [e-f] should be

[e=C3=A8=C3=A9=C3=AA=C3=AB=C4=93=C4=95=C4=97=C4=99=C4=9B=C8=85=C8=87=C8=A9=
=E1=B8=95=E1=B8=97=E1=B8=99=E1=B8=9B=E1=B8=9D=E1=BA=B9=E1=BA=BB=E1=BA=BD=E1=
=BA=BF=E1=BB=81=E1=BB=83=E1=BB=85=E1=BB=87f=C6=92]

iff e unfolds to the same set as =C3=AB. If e only unfolds to [e], then
[e-f] would unfold to [ef].

Does that sound sane?
