This is my LaTex script:
\documentclass[a4paper]{article}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{Jenson Classico}
\begin{document}
ąęśćłó
\end{document}
I compile this using xelatex through eclipse plugin.
As Jenson Classico has no polish characters I have edited this font to add them. In Microsoft Office it works fine (I am able to use polish characters). Unfortunately in pdf generated from above tex-file it doesn't. If I use any other font (e.g. Arial) it works like a dream.
Any suggesions? I really don't have any more ideas...
