The Unicode Technical Committee has posted a new issue for public review
and comment. Details are on the following web page:
Review periods for the new items close on October 28, 2005.
Please see the page for links to discussion and relevant documents.
Briefly, the new issue is:
80 Proposed Update to UAX #9: The Bidirectional Algorithm
The Unicode Bidi algorithm has allowed for a great deal of flexibility in
determining which characters are to be mirrored (see HL6
http://www.unicode.org/reports/tr9/tr9-16.html#HL6). Unfortunately, that
means that text that originates with one person may show up with the wrong
graphic to another, thus causing the text to be misinterpreted. The
proposal is to tighten up conformance by limiting overriding to
mathematical contexts, and at the same time adjusting the characters with
the Bidi_Mirrored property.
The UTC would like public feedback on whether to make this change, and
which characters should have the Bidi_Mirrored property. The following is a
possible change to the properties which bases the Bidi_Mirrored on the
open/close punctuation in Unicode. It excludes the math characters
(General_Category=Sm); implementations could tailor those characters to
mirror in a mathematical context. For further information and character
lists, see the background document for this issue.
