If the direction should happen to be right-to-left, not only is the game mirrored, but the board edges don't work properly, as the glyphs are not mirrored.  One needs each bidi-paragraph to be forced to the correct order, e.g. by use of LRM before and after, or, if the board is recorded right-to-left, RLM or ALM before and after.

None of the characters listed in §3 has a mirroring property.
