Hi, a bididirectional text layout question...
What is the correct display order of the logical sequence
when the global direction is right-to-left.
ref. the Unicode Standard V1.0 Volume 1, page 618, "Resolving Implicit
"if the global direction is odd (right-to-left) then the
left-to-right text and numeric text (EN or AN) goes up one level".
In this case the embedding levels for the above sequence are "122".
After reordering level 2 this gives
and after reordering level 1 gives the final result
Microsoft Arabic Windows displays this sequence as
when the reading order is right-to-left (I assume that global direction
is the same thing as reading order).
Who is right? Arabic Windows supposedly implements the Unicode algorithm.
Arabic Windows and Unicode agree on the layout of this
sequence when the global direction is left-to-right, ie
