Proposed Update Version 5.0 of UTS #51, Unicode Emoji is available for public review and feedback. This new version is slated to be a Unicode Technical Standard, and thus adds a conformance section and related definitions.This new version adds a mechanism to support regional flags, such as Scotland or California, although the choice of which of these flags to support is left to vendors beyond a recommended set of three. UTS #51 will have a separate data file for the valid emoji presentation sequences. It also reflects some changes to the recommended sort order that will be released soon in CLDR v31. For more details, see the Modifications section of the document.
