I see all the unrecognised fonts ("arial" and 'century gothic' with quotes, webdings, asdfrandomstuff) as palatino linotype, which is the default font I set for my browser. The serif font is the same; the sans-serif font I see as arial, which is the default sans-serif font I set.
The last one you should see as arial:
CODE
[font=randomstuff2, arial]randomstuff2, arial[/font]
So yes, it works like html/css works - if the browser doesn't recognise the font, it displays the text in your default font. But don't put fonts in quotation marks.
