Re: [alreq] Vertical text handling in Unicode

My guess is that it has to do with it being significantly simpler to implement, especially in environments where the length of the line can be randomly altered by the user. The CSS approach means that the line-break point is always at the bottom of the line. It also makes it easier to handle combinations of Latin text embedded within Arabic, since they both share the same orientation and the directional layout is the same as for horizontal text (just on it's side). 

@behnam do you have examples of arabic text in vertical set lines of CJKM? (Note that i'm not referring to book spines, table headers, etc, since those would use writing-mode: sideways-lr/rl)
