Announcing The Unicode Standard, Version 6.3

<http://www.unicode.org/versions/Unicode6.3.0/>

The Unicode Consortium announces Version 6.3 of the Unicode Standard and
with it, significantly improved bidirectional behavior. The updated
Version 6.3 Unicode Bidirectional Algorithm now ensures that pairs of
parentheses and brackets have consistent layout and provides a mechanism
for isolating runs of text.

Based on contributions from major browser developers, the updated
Bidirectional Algorithm and five new bidi format characters will improve
the display of text for hundreds of millions of users of Arabic, Hebrew,
Persian, Urdu, and many others. The display and positioning of
parentheses will better match the normal behavior that users expect. By
using the new methods for isolating runs of text, software will be able
to construct messages from different sources without jumbling the order
of characters. The new bidi format characters correspond to features in
markup (such as in CSS). Overall, these improvements also bring greater
interoperability and an improved ability for inserting text and
assembling user interface elements.

The improvements come with new rigor: the Consortium now offers two
reference implementations and greatly improved testing and test data.

In a major enhancement for CJK usage, this new version adds standardized
variation sequences for all 1,002 CJK compatibility ideographs. These
sequences address a well-known issue of the CJK compatibility ideographs
--- that they could change their appearance when any process normalized
the text. Using the new standardized variation sequences allows authors
to write text which will preserve the specific required shapes of these
CJK ideographs, even under Unicode normalization.

Version 6.3 includes other improvements as well:

    * Improved Unihan data to better align with ISO/IEC 10646
    * Better support for Hebrew word break behavior and for ideographic
      space in line breaking
