# Getting vinculum in fractions with Asana Math and unicode-math

With this minimal example

\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmathfont{Asana Math}
\begin{document}
$\frac{2\pi r}{r} = 2\pi$
\end{document}


I am unable to get the horizontal bar or vinculum for the fraction on the left.

I am new to unicode-math, and want to use the Asana Math font with Minion Pro as my main font, compiling the document with xelatex.

Can someone please suggest what is wrong and how to correct it?

Many thanks.
