The Unicode Consortium is soliciting feedback on the text and data changes in the following proposed update specifications. These specifications are synchronized with Unicode Version 11.0, and slated for release at the same time, in early June. Feedback is due by April 23 — this is the last chance to provide feedback on any changes and any open review issues.
UTS #39, Unicode Security Mechanisms updates data for Unicode 11.0, adds a new
section describing the handling of Joining Controls (ZWJ and ZWNJ), and adds
tests to Section Section 5.4 Optional Detection for checking nonspacing marks
UTS #46 Unicode IDNA Compatibility Processing updates data for Unicode 11.0, and
extends the format of the test data file. The new test format allows
implementations to determine more precisely where any validity test fails, and
allows the implementation to filter for the exact combination of supported
UTS #10 Unicode Collation Algorithm updates data for Unicode 11.0, and otherwise
makes no material changes to the text.
Details of the Unicode 11.0 Beta and open Public Review Issues are available on the Unicode website.
