RE: [BULK] - Re: Vertical BIDIThere are two things someone could mean by 'vertical bidi':
a. mixing lines of different direction.
b. as Mike says, within a vertical line, mixing characters of different directionality.
What the Bidi Algorithm says both of these is at:

"Vertical bidi" refers to the mixing of top to bottom(TTB) and bottom to top(BTT) (note ironic mirrored nature of acronyms, which is unintentional, and therefore all the more delicious) scripts in a vertical layout. We had significant disussion of this issue. I was not able to follow all of it, but what I noted was that it lead to several people trying to determine a plausible case in which vertical bidi would be needed. I am not certain what the conclusion was there - anyone?
In any case, you could generally use the standard bidi algorithm for vertical bidi by simply defining a reference direction. There may have been more to it than that - again, I don't quite recall fully. Once it became clear that a case of vertical bidi would only arise if someone forced the issue, I lost interest.
