I see a big difference between the two cases. Right-to-left vs. left-to-right are attributes of arbitrary *spans* of text, which can easily be mixed within the same paragraph. On the other hand, horizontal vs. vertical are attributes that can be only be applied to a whole paragraph or section. So, an hypothetical pair (start/end) of top-to-bottom override character should probably also act as paragraph separators. I wish a decent 2002 to everybody (as wishing more than "decent" would be quite irrealistic). _ Marco
