Most platforms have some way to define new keys:  on Unix with X11 you can
use Xkb or xmodmap (the keysym for a Unicode character is the codepoint
expressed as a hex constant, so 0x2218 for ∘), and there are a handful of
Xkb editors out there; on OS X you can use keyboard substitutions (Language
& Text > Text) or use a program such as Ukelele to modify the keyboard
layout; I don't know specifics for Windows, but at its lowest level there
are registry tweaks and there should also be programs to do those tweaks in
people-comprehensible ways.
