[tex-live] \string in xetex

I asked a similar question on the xetex list but I wonder if anyone here
has a better grasp than me on the use of utf16 v utf 32 in xetex.web and
can offer any insight into the use of \string in xetex.

The attached file produces a log of

A=B
A=C
A=D
A=E
B=C
B=D
B=E
C=D
C=E
D=E


with luatex, but with xetex it produces

! Undefined control sequence.
l.6 \edef\c{\string��
                       }
?
! Undefined control sequence.
l.10 \edef\e{\string��
                        }
?
A=B
C=E
 )


which is clearly pretty wrong

(\string is producing two tokens with the UTF-16 representation,
rather than one token)


I don't think it's a show stopper for TL2015 as it's always been that way
as far as I can see, but it would be nice to fix it, but my attempts to do
so have taught me a lot about the web sources but not produced anything
usable.
