Do you mean, that LRM/RLM should be added to the text buffer? If no, can
you,please, explain, what do you mean? If yes, you understand, that using
bidi markers needs additional logic in GTK application. It is good for some
specific cases, but not always. What I really want here is simple API (in
the widget level), which allows to switch from contextual (default)
ordering to the "strong" ordering, that corresponds to current widget
direction.
