For some strange reason, I get errors in the following file: \documentclass[12pt]{article} \usepackage{fontspec} \setromanfont[Mapping=tex-text]{Gentium} \begin{document} Price 25\$\ or 25€. Romeo \&\ Juliet. Backslash (\\{}) \end{document} '&' is escaped right, but '\' and '$' aren't. Am I missing something or is it a bug in the Linux version? Thanks, Pablo
