I want to do something like
font-family: font1, font2, font3
fonts 1 and 2 cover the common stuff, 3 an alphabet not covered by 1 and 2.
Given a latin glyph it will use 1 if available, if not it will use 2.
Given a glyph from the other alphabet I want it to use 3. Will all browsers do this or will some try to fallback to something else?
