[arabic-vip] Fwd: PRI #185: Revision of UBA for improved display of URL/IRIs

[Behnam Esfahbod]

Unicode has published a public review request for an "extension" to Unicode
Bidirectional Algorithm for URL/IRIs.

This extension is supposed to resolve one of the issues that we have been
talking about. In my opinion, it's generally a good step forward, but this
extension may create further inconsistencies, like different behaviors for "
ABC at XYZ.COM" and "mailto:ABC at XYZ.COM" in a plain text (where capital letters
are RTL letters).

What do you think about it?

Subject: PRI #185: Revision of UBA for improved display of URL/IRIs
To: announcements at unicode.org


The Unicode Technical Committee has posted a new issue for public
review and comment. Details are on the following web page:

   http://www.unicode.org/review/

Review period for the new item closes on July 27, 2011.

Please see the page for links to discussion and relevant documents.
Briefly, the new issue is:

PRI #185    Revision of UBA for improved display of URL/IRIs

The Unicode Bidirectional Algorithm (UBA), specified in UAX #9, was
designed for handling ordinary text, and predated the rise of the web.
Unfortunately, IRI/URLs are not ordinary text; they are syntactically
complex in ways that don’t work well with the UBA. That causes IRIs
that contain right-to-left text (such as Arabic or Hebrew) to appear
jumbled, to the point where the IRIs are either uninterpretable,
misleading, or ambiguous. In particular the ambiguous displays could
cause security problems.

The background document for this PRI provides a detailed description
of the problem, and proposes a solution. The Unicode Technical
Committee would like feedback on the feasibility of the proposal, and
in particular, on the open issues listed in the background document.
