Non-ASCII characters Key binding (emacs 21.4)

[Mounir AITTAHAR <mounir.aittahar@fri.fr>]

Hi,

On emacs 20.7 (yes), i wrote some lisp functions in order to
subsitute local characters (like é, ô) with sgml values (like é, 
ô) or LaTeX corresponding sequences (like \'e,\^o).

Theses functions looked like :

(local-set-key (vector 233) ;
                   (lambda()(interactive)(sgml-name-char 233)))
Or,
(local-set-key (vector 233)
                   (lambda()(interactive) (insert "è")))


On emacs 20.7, it worked. On emacs 21.4, it doesn't work more.
I've tried to found why trough Google search, tried several way likee
but nothing.

233 is the value of "grave e" character.

I'm using a vector because it is told on the description of 
local-set-key , and to prevent the problem of multibytes
characters (GNU Emacs manual : 
http://www.gnu.org/software/emacs/elisp-manual/html_node/elisp_333.html).

What have i done wrong ? Is this a known problem ?

Thanks and regards,
