There are three issues here: (1) reproducing the Word doc layout
faithfully in AW; (2) from the AW user's point of view having a
consistent BIDI behaviour irrespective of the document format; (3)
exporting the document to rtf/doc in a manner that will ensure faithful
layout when viewed by Word.
I think the only way to satisfy both (1) and (2) is for the MSWord
importer to insert explicit direction overrides based on the version of
Word that created the document so that the bidi ordering when
processed with the Unicode algorithm would be the same as that
produced by Word on that document. In any case, dealing with this
no trivial.
