Version 3.0 of
UTS
#39, Unicode Security Mechanisms has been released by the
Unicode Consortium, together with a new version of the associated
UTR #36, Unicode
Security Considerations. Because the Unicode Standard contains
such a large number of characters for the writing systems of the
world, caution is necessary to avoid exposing programs and systems
to possible security attacks. These revised documents describe
security considerations for Unicode and specify improved mechanisms
for reducing the risk of problems.
Version 3.0 is a major revision. Significant changes include:
-
Mixed Script Detection has extensive revisions to its
specification.
-
Restriction Level now has an explicitly defined process.
-
Mixed Number Detection now has an explicitly defined process.
-
Conformance requirements have been extended to include Restriction
Level and Mixed Number Detection.
