[XeTeX] Typesetting Greek mathematical text using Unicode

[d fulano]

Many thanks for your replies, the suggestions work perfect!


I have another strange problem. When I try to use the following code


 

\documentclass[a4paper]{article}
\usepackage{xltxtra}
\setmainfont{Cambria} 
\begin{document}
Ἀριθμὸς  \char"1F08
\end{document}

 

I get for character "1F08 Greek Capital Letter Alpha with Psili" 

something that looks like A' with the accent to the right, not the left. 

 

With Arial font, I get the correct letter. 

 

Is there something wrong with the font itself, or with how XeTeX uses the font?

 

I have not installed any fonts, it's just the Cambria font that Word has. 

In Word, 'A looks correct when I insert symbol 1F08

 

Thank you
