Unicode emoji characters are specified by UTR #51, Unicode Emoji and its related data files. Now available for public review and comment are a proposed update of UTR #51, plus a draft of a related new document, UTS #52, Unicode Emoji Mechanisms.
UTS #52, Unicode Emoji Mechanisms provides a new way of representing
customizations of Unicode emoji characters. The first specified
customizations provide for flags for subdivisions of countries (such as
Scotland or California), gender variants (such as female runners or males
raising a hand), hair color variants (a red-haired dancer), and directional
variants (pointing a hand or bicyclist to the right). Currently this is only
a draft, but feedback is being solicited on a number of topics. From users
of emoji, feedback would be useful on which variants are the highest
priority, and whether any characters should be added or removed to the lists
of characters that qualify for each variant. From implementers, feedback is
needed on whether there are any technical problems in the customization
mechanism itself, and whether that mechanism is sufficiently extensible for
future types of customizations.
The proposed update UTR #51, Unicode Emoji
describes two new
mechanisms for controlling whether emoji characters appear as text (black
and white) or with a colorful rendition, and clarifies some of the previous
text. There is also a proposed narrowing of the definition of the sequences
used for family groupings.
Feedback must be submitted through the associated
Public Review Issues by May 1 for consideration at the 2016Q2
Unicode Technical Committee meeting.
