This actually seems to work with the current implementation!  My
assumption of what the correct result ought to be seems to be wrong.

  (bidi-reorder-string
   "I SAW A f14 FLYING BY."
   (bidi-resolve-implicit-levels
    (bidi-resolve-weak-types
     (bidi-get-types "I SAW A f14 FLYING BY."))))

 => "A WAS I f14 YB GNIYLF."

This seems to be working as expected as well.

  (bidi-reorder-string
   "he said \"I AM GOING TO london TODAY\"."
   (bidi-resolve-implicit-levels
    (bidi-resolve-weak-types
     (bidi-get-types "he said \"I AM GOING TO london TODAY\"."))))

  => "he said \"OT GNIOG MA I london YADOT\"."

Now I am completely confused.  It seems that I can apply my code
(which essential does logical to visual according to UAX#9 without
taking explicit directional types into account) to visual order text
and get the correct logical representation.  I'm not sure wether that
result is entirely expected.  :)
