A new proposed update of UTS #39, Unicode Security Mechanisms is now available for public review and comment.

The proposed update of this Unicode Technical Standard includes new material for email security profiles and text about the use of Script_Extensions. The data file confusablesWholeScript.txt has been withdrawn, because in practice the process of derivation of whole script confusables depends on the particular set of characters supported by an application. The use of a data file is replaced by a logical process of deriving the whole-script confusables data based on the set of supported characters.
