No, reversing the string only undoes what the simulated rendering
does: it draws the glyphs starting at the right display margin
instead of the left.

Hm.. it seems that the simple rule I suggested is indeed incorrect.
SOmething more complex is needed: we need only to look in the other
direction when the character belongs to a substring that was reversed
odd number of times.
