rebind the é key the command which works is
(global-set-key [2281] 'foo)
the command
(global-set-key "é" 'foo)
does not work.
Since you have a working command, I guess this question is partly out
of curiousity... so I don't feel bad about suggesting something that
I'm not sure will help, but - out of curiousity, what does
(kbd "?")
return?
BTW, here, in a buffer with coding system described by
(describe-current-coding-system) to be
Coding system for saving this buffer:
Not set locally, use the default.
Default coding system (for new files):
nil
Coding system for keyboard input:
nil
Coding system for terminal output:
nil
Defaults for subprocess I/O:
decoding: - -- undecided
encoding: 1 -- iso-latin-1 (alias: iso-8859-1 latin-1)
a *local* binding to "?" works fine.
