That depends on how/where you output the data, obviously. If you're writing a 
GUI app or a webpage you can, of course, go as crazy with the font as you 
want to.
In terminal apps you don't have control about font size or face. Changing 
color, inverting color or underlining is possible, but terminal dependant 
(specifically I don't think the terminal in Windows handles ANSI escape 
sequences). There probably are gems to abstract away the differences between 
platforms, though.


HTH,
Sebastian
