http://www.purl.org/tcl/home/man/tcl8.4/TkCmd/keysyms.htm describes what key symbol values can be used with bind (any other commands?).
[What is a key symbol?]
Open a wish session and type
bind . <KeyPress> {puts %K}
Then press any key or key combination to learn the keysym for your desired key binding
Is there any way to use accented characters (as used in many European languages) in bindings? I want, for example, Alt-e' (meant to be Alt pressed with an accented e) to be bound to a command. -- CLN 2001-06-11

would seem to do what you want, but possibly only if you actually have a � key to press. At least for me, characters composed with dead keys don't fire the bindings, but character keys (e.g. adiaeresis on my keyboard) do.
