I will give you a quote (albeit with some delay) from the book:
Most of the problems arise in the fantasy family, because it gets any font that does not belong to the four other families. It is difficult to imagine what characters will be displayed on the screen. Another problem-generating value is cursive ...
etc. etc. Further, it is not very interesting, but one thing can be noted - Comic Sans refers to fantasy fonts. If a paragraph is displayed to you in italics, the following is obtained: the browser cannot find the first font and displays the contents in the font whose family is specified last.
PS but in general I also have everything displayed. Even in IE 8 ...)))
