  Actually no, it expects you to use the non-breaking space (U+00A0
NO-BREAK SPACE) as a digit separator instead of the normal space.
Sequences of digits interspersed with non-breaking spaces are not
reordered by the Bidi Algorithm, contrary to what happens when you use a
normal space.

  Of course this is not practical in ConTeXt for the moment, as the
non-breaking space isn't treated as such (or is it?).
