I don't know how many people already know about this, but there is this thing that one can do with the Alt key to have any representable ascii character show up without any fancy work. Simply holding down Alt, then typing in the numeric value will show the character. Interestingly enough though, in ICQ, nothing with the number 3 in it will work without immediately shutting the current window. It doesn't do it in AIM though. How very odd.
