[XeTeX] \textfractionsolidus undefined in EU1?

[Alex Lubberts]

Hi,

If I run this file:
-----
\documentclass[dutch,a4paper,12pt]{article}

\usepackage{babel}
\usepackage{euler,fontspec,graphicx}
\usepackage{xunicode}
\usepackage{xltxtra}

\defaultfontfeatures{Scale=MatchLowercase,
                     Mapping=tex-text,
                     Numbers={OldStyle,Proportional}}
\setromanfont{Chaparral Pro}
\setsansfont{Myriad Pro}
\setmonofont{Courier Std}

\begin{document}
Vfrac doesn't work: \vfrac{12}{14}.
\end{document}
-----
the following error occurs:

./test.tex:16: Emergency stop.
\EU1\textfractionsolidus ->\undefined

Seems like \vfrac stopped working because \textfractionsolidus isn't
defined (yet)?

Regards,
Alex
