Bonjour,

Who can explain (and correct if possible) this strange behaviour of the
Linux Libertine fonts if you add the option "Fractions=On"

If you put a number with more than one digit,  only the last number has
the normal size, the preceding digits are written like exponants before it.

\documentclass[11pt]{article}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text,Fractions=On]{Linux Libertine O}
\begin{document}

12 34 56 2900

\end{document}

Suppress the option "Fractions=On" and everything is OK...

Thanks for helping.
