When trying to get it using firefox or chrome on Windows it looks ok:

But when I try getting it from firefox or chrome on Ubuntu all the Hebrew is showen incorrectly. It replaces them with characters like "יס פל×× ×˜ - ×ילון":

I checked on windows and the font seems to be monospace, which is standart.

I there a way to solve it? Thanks!
