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: http://tug.org/pipermail/xetex/2010-November/019236.html Anyone have a solution?
