Hello,

Is Unicode's so-called "bidi algorithm" really bidirectional, that is, does it govern 
horizontal text layout in right-to-left and left-to-right languages?  

Or is "bidi" a metaphor here, for more possible text orientations, including vertical 
boustrophedons and other historically available options?  I'm asking because I tried 
to read the Unicode 3.0 paper documentation and wasn't sure what it was saying at some 
points.

Also, on the Internet, are historically vertically placed languages being written 
vertically?  Some of them are BOTH vertical and right to left...........How difficult 
is this technically?
