Hi all (yes, it's me again!):
If I compile this file:
\documentclass{article}
\pagestyle{empty}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\begin{document}
---
\end{document}
with XeLaTeX, then I get a PDF file which contains a single character,
namely an em-dash. But if I add, say, \setmainfont{Arial} before
\begin{document}, then what I get is ---. Why? Do I have to use
\textemdash instead?
Best regards,
Jose Carlos Santos
