Cambria Math and Neo Euler (not using local copies, but from the Fonts

Thank you very much, Michael Lynch and Khaled Hosny, for very helpful
comments, and Will Robertson -- for his posting (on my behalf) which led
to the workaround suggested by Mike.

That was very helpful indeed. I confirm to have Asana-Math.otf both in the
system font directory C:\Windows\Fonts and in my MiKTeX 2.8 tree. (the
latter must have been installed without me ever noticing it when I was
upgrading from MiKTeX 2.7 to 2.8; before, when I had Asana Math only in my
system font directory I wasn't experiencing the described problem).

I didn't have to remove Asana-Math.otf from C:\Windows\Fonts. I just
followed Mike's suggestion and replaced

\setmathfont{Asana Math}

by

\setmathfont{Asana-Math.otf}

in my XeLaTeX source file.

No more off-by-one shift in character mapping. Everything looks as it should.

Many thanks to Will Robertson for his 'unicode-math' package and to
Apostolos Syropoulos for Asana Math.
