FYI: In gvim 9.0.32 (Big, GTK3) i.e. without this patch, with Belgian
keyboard on openSUSE Tumbleweed, in Insert mode, Ctrl-V followed by
Ctrl+AltGr+dead-circumflex inserts an Esc character (displayed as ^[
in blue) into the buffer.

This is, however, a complex keychord. It is also possible to assign
<Esc> as the {rhs} of a mapping.

Best regards,
Tony.
