#121: BIDI: Some users are requiring right-to-left label ordering.


Comment (by duerst@…):

 Hello Shawn,

 Two points of clarification:

 - At http://trac.tools.ietf.org/wg/iri/trac/ticket/121#comment:4, you
 write "Indeed, the proposed behavior uses bidi override marks to get the
 desired behavior.", but it's not override marks, it's embedding marks.
 Otherwise, not a single RTL domain label or path component would be
 readable. (maybe that's what you meant, but in that case, please be
 careful with terminology)

 - At http://trac.tools.ietf.org/wg/iri/trac/ticket/121#comment:7, you
 wrote about partial web names in all-Arabic on the side of a bus, e.g.
 CCC.BBB.AAA. In this specific case, the current spec (RFC 3987 and draft-
 ietf-iri-bidi-guidilines-02.txt) will do the right thing (because the
 Unicode Bidi algorithm reorders by runs, not by components). In that case,
 no embedding may be necessary. This is explicitly mentioned:

 {{{
                                                          Also, a
    bidirectional relative IRI reference that only contains strong right-
    to-left characters and weak characters (such as symbols) and that
    starts and ends with a strong right-to-left character and appears in
    a text with right-to-left base directionality (such as used for
    Arabic or Hebrew) and is preceded and followed by whitespace and
    strong characters does not need an embedding.

 }}}
