menus with non-english language

[aegis]

hi, i wanted to create a menu with options written in greek so i wrote something like this::

anAction= new QAction("Επεξεργασία", this);
 
or
 
anAction= new QAction("Greek words...", this);

anAction= new QAction("Επεξεργασία", this);

or

anAction= new QAction("Greek words...", this);

To copy to clipboard, switch view to plain text mode 

but when i tried to run the program the menu had rubbish....

how can i fix this problem?
