The event-reading functions invoke the current input method, if any
(voir la section Input Methods). If the value of input-method-function is
non-nil, it should be a function; when read-event reads a
printing character (including <SPC>) with no modifier bits, it calls
that function, passing the character as an argument.
If this is non-nil, its value specifies the current input method
function.
Warning: don't bind this variable with let. It is often
buffer-local, and if you bind it around reading input (which is exactly when
you would bind it), switching buffers asynchronously while Emacs is
waiting will cause the value to be restored in the wrong buffer.
The input method function should return a list of events which should be
used as input. (If the list is nil, that means there is no input, so
read-event waits for another event.) These events are processed
before the events in unread-command-events (voir la section Miscellaneous Event Input Features). Events returned by the input method function are not passed to the
input method function again, even if they are printing characters with no
modifier bits.
If the input method function calls read-event or
read-key-sequence, it should bind input-method-function to
nil first, to prevent recursion.
The input method function is not called when reading the second and
subsequent events of a key sequence. Thus, these characters are not subject
to input method processing. The input method function should test the
values of overriding-local-map and
overriding-terminal-local-map; if either of these variables is
non-nil, the input method should put its argument into a list and
return that list with no further processing.
