# Combining unicode-math fonts: Problems with \underbrace [closed]

I switched to XeLaTeX and unicode-math a while ago. I really like the possibility to combine different fonts for mathematical symbols. But now I run into trouble by combining the \underbrace command with content from different fonts. I actually use Asana as my main math font, but don't like its \underbrace, as these are too wide and with too much space between itself and the content. Therfore I wanted to use some from another font, which gave some grapy output:

\documentclass[]{scrartcl}

\usepackage{amsmath}

\usepackage{polyglossia}
\setmainlanguage[]{english}
\setotherlanguage[spelling=new,babelshorthands=true]{german}

\usepackage{unicode-math}
\setmathfont{Asana-Math.otf}

\begin{document}
Asana math Blubb
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[]{xits-math.otf}
XITS math
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[]{Cambria Math}
Cambria Math
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[]{latinmodern-math.otf}
Latin modern
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[]{texgyrepagella-math.otf}
Neo Euler
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
Asana as math font, change font for underbrace only:
\setmathfont[]{Asana-Math.otf}
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[range=\mathunder]{xits-math.otf}
XITS math
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[range=\mathunder]{Cambria Math}
Cambria Math
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[range=\mathunder]{latinmodern-math.otf}
Latin modern
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\setmathfont[range=\mathunder]{texgyrepagella-math.otf}
Neo Euler
$\underbrace{1} \quad \underbrace{1+1} \quad \underbrace{1+1+1} \quad \underbrace{1+1+1+1} \quad \underbrace{1+1+1+1+1}$
\end{document}


Is there any workaround for this? Or is it in general no good idea to combine different math fonts?

I'm in general not so sure if to stay with unicode-math, as the compilation speed slows down, and for example the XITS font has much too narrow spacing sometimes (using XeTeX, Version 3.1415926-2.4-0.9998, MiKTeX 2.9)

Annotation

According to the first comment I just tried the TeX Gyre Pagella Math which also seems to be a nice font with better underbraces than Asana-math. But this brought me just to another behavior of unicode-math with XeLaTeX I have noticed before already but forgotten about. If I run the following code:

\documentclass{article}

\usepackage{amsmath}
\usepackage{unicode-math}
\setmathfont{texgyrepagella-math.otf}

\begin{document}
Test.
\begin{align*}
\end{align*}
\end{document}


Some minor changes that do not directly affect the math environment can change this behavior:

\documentclass{article}

\usepackage{amsmath}
\usepackage{unicode-math}
\setmathfont{texgyrepagella-math.otf}

\begin{document}
\begin{align*}
\end{align*}
Some text.
\end{document}


I once got a similar behavior when I did a beamer presentation (using Asana-math, if I remember correctly) where changes anywhere in the TeX code could affect the braces in the shown way. I thought that this would maybe depend on the special circumstances of using beamer, but apparently hopping underbraces can appear anytime. Did anybody else see such a behavior of the \underbrace command before?

You should try TeX Gyre Pagella Math instead of Asana Math –  egreg Aug 27 '13 at 15:34
Thanks. Looks good and I will give it a try. –  Hypnotoad Aug 27 '13 at 18:33
The shifting braces is a big that was fixed in XeTeX 0.9999. –  Khaled Hosny Aug 27 '13 at 21:12
This is good new, but until now I avoided updating due to link –  Hypnotoad Aug 28 '13 at 8:59
This question appears to be off-topic because it is about a bug which is now fixed. –  Joseph Wright Sep 7 '13 at 21:48
