Well, in a normal HTML environment, you'd use the named character entity ø (from this full list of name character entities), but since HTML stuff has been disabled here, then you just have to insert the 8-bit character manually and hope that whoever's viewing it is using the same character encoding (ISO-8859-1, etc.) that you are. Under MSWindows, the easiest way to find a character is to pull up the Windows Character Map (try Start->Programs->Accessories->System Tools) and find it in there.
