Consider
RLE a b c PDF RLE d e f PDF
in an LTR region (where a, b, ... are neutral). This displays as
cbafed
i e, 2 RTL runs in LTR order. If you encode that as
a b c d e f
1 1 1 1 1 1
it's indistinguishable from
RLE a b c d e f PDF
which displays as
f e d c b a

So I don't see how this can work. Am I missing something?
