There's different versions of the "basic" fonts (like Times or Arial). Since version 2.76, for example, Arial supports Hebrew characters (as stated here
http://www.slovo.info/unifonts.htm). So you can download the right version of the fonts (on the corefonts project there, for example
http://sourceforge.net/project/showf...ease_id=105355), and install them on your machine.
