Asana Math 000.928

(via TeX Live).

My source file is

%%!TEX TS-program = xelatex
%%!TEX encoding = UTF-8 Unicode
\listfiles
\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmathfont{Asana Math}
\begin{document}
$\frac{2\pi r}{r} = 2\pi$
\end{document}

(the first two lines are read by TeXShop).

Good Luck,
