Fine by me.  I haven't looked at the Fribi Tests, so I will do that
now.

No, when I convert them they turn into a logical representation which,
if the reverse operation is applied, does not yield the original text.
This is what Ehud expected.  Ehud then proposed an idea involving the
insertion of additional LRM characters.  I'm still not sure I
understood how it was supposed to work, but I wrote that already in
another mail.

As to punctuation etc. I am pretty confident that my implementation
will have the exact deficits to be expected from a UAX#9
implementation.

What follows are blocks of three lines.  The first line lists the
example Ehud proposed, the second line has the result in an
left-to-right context, the third lists thre result in a right-to-left
context.  I produced these by calling M-x
bidi-visual-to-logical-paragraph and answering left-to-right or
right-to-left respectively.
