keyboard: accented letters not working

Dear Buildroot friends,

On a BR system:

- kbd_mode reports that the keyboard is in Unicode (UTF-8) mode

- French layout has been loaded: it's azerty and not qwerty

- Still, accented letters do not work: typing ? produces {, typing ? produces ^i, etc.

Any idea about what could be misconfigured,please?

Many thanks!

Sh?rab.
