Variable: bidi-display-reordering
bidi-display-reordering is a buffer-local variable defined in
buffer.c.
Documentation
Non-nil means reorder bidirectional text for display in the visual order.
Setting this to nil is intended for use in debugging the display code.
Don't set to nil in normal sessions, as that is not supported.
See also bidi-paragraph-direction; setting that non-nil might
speed up redisplay.
Probably introduced at or before Emacs version 24.1.
