This draft on internationalized URIs:

    http://www.w3.org/International/iri-edit/draft-duerst-iri.html#anchor5

points out some examples of extremely confusing display orders that
can be caused by digits (which require a left-to-right ordering),
slashes (which can cause digits to be interpreted as fractions), and
other operators near digits.  These strike me as rather awful results
of the bidi algorithm.

Would the display of source code be affected this way as well?
