\underbar produce incorrect output

[blubbafett]

Check the PDF's at http://folk.ntnu.no/mitrevsk/temp/xits_bug/

The problem appears with both XeLaTeX and LuaLaTeX (using TL2010 pretest in Windows7).

Code used;

\documentclass[12pt,a4paper]{article}

\usepackage{amsmath}
\usepackage[bold-style=upright]{unicode-math}
\setmainfont{XITS}
\setmathfont{XITS Math}
\begin{document}
\begin{equation}
\underbar{\mathbf{I}} = \left[\mathbf{I}_1\,\mathbf{I}_2\,\ldots\,\mathbf{I}_K\right]^\textup{\textsf{T}}
\end{equation}
\end{document}

This a unicode-math bug, please report to unicode-math.

P.S. Please surround your example with ‘pre’ HTML tags or indent it with four spaces to print code correctly

@Khaled: I see it now (sorry for not testing with other UM-fonts first). Also fixed the example code. I also see that you have reported there yourself. Should I just try to write under your post, and see if someone does anything about it or?

[khaledhosny]

BTW, your \textup{\textsf{T}} ends up using CM sans not the math sans from the math font, no idea why.

[wspr]

Because \textsf chooses the text font and \mathsf chooses the math font :)

Ah, thanks for telling! Learning something new everyday; didn't know that \mathsf yileded upright text.
