Console doesn't render according to man manual

So why is my console on Ubuntu doesn't render according to the man manual? If I type in man man in the console I get a manual for man. And for example, it points out that italic text replace with appropriate argument. But what I can see is a string *italic text* which is underscored. Why the example is not in italics and why it is underscored? Is it like this or is it because my console renders text in another way than others, so someone may see text in italics?
