Using \underbrace with the unicode-math package under XeLaTeX produces
garbage output. Here is a minimal example:
\documentclass{book}
%\usepackage{mathspec} % no problem
\usepackage{unicode-math} % problem
%\setmathfont{lmmath-regular.otf} % |{z}
%\setmathfont{Asana-Math.otf} % ||{z|}
\setmathfont{xits-math.otf} % |{z}
\begin{document}%
\[ \underbrace{xyz} \]
\end{document}%
Using the mathspec package instead of unicode-math seems to be OK.
The \underbrace with unicode-math problem was discussed almost one year ago:

Anyone have a solution?
Many thanks in advance,
Dan
