We don't support that. From display_mode_line:
/* FIXME: This should be controlled by a user option. But
supporting such an option is not trivial, since the mode line is
made up of many separate strings. */
it.paragraph_embedding = L2R;
and a more complete rationale in redisplay_tool_bar:
/* FIXME: This should be controlled by a user option. But it
doesn't make sense to have an R2L tool bar if the menu bar cannot
be drawn also R2L, and making the menu bar R2L is tricky due
toolkit-specific code that implements it. If an R2L tool bar is
ever supported, display_tool_bar_line should also be augmented to
call unproduce_glyphs like display_line and display_string
do. */
Bottom line: Emacs doesn't support making the UI right-to-left.
IMNSHO in IME, supporting that would be a lot of work for very little
benefit.
