I am using Gedit and LibreOffice Writer. When I want to write in Hebrew I don't have any problem. When I download a LibreOfiice file in Hebrew I do not have any problem, either. When I download a file that is not a LibreOffice file (which means I am opening it with the Gedit) all I see is
àðà äùàéøå ùí åîñôø èìôåï.
Why is that? Is it because I am opening a file with ".str"? Here is an example of website which from there I downloaded the file.
