What's new in Unicode 8.0 ?

Previously discussed :


[Unicode 8.0 was released on 17 June 2015]

The Short Answer

IT'S THE TACO, STUPID !


picture of a taco emoji


Yes, the taco emoji will be encoded in Unicode 8.0 in June of this year at U+1F32E with the name taco ...

... and if that's all you care about you can go away contented now. And by the way, someone please kill the utterly pointless Taco Emoji Needs To Happen petition. I mean, why have a petition addressed to the Unicode Consortium if you are not going to deliver it, or at least not deliver it until you have some arbitrary number of signatures, which at the current rate will be six months after the Taco emoji has already been encoded ?!



The Long Answer

Unicode 8.0 will be released in June 2015, and is the second version of Unicode to be released under the new annual, fixed-date release schedule. As you can see from the top of this post, previous major versions of Unicode have been released at various times of the year and at various intervals. Until further notice, a new major version of Unicode will be released in June of each year (so expect Unicode 9.0 with Tangut in June 2016). This predictable release schedule will help harmonize the Unicode standard with ISO ballot process for the corresponding international standard, ISO/IEC 10646. Unicode 8.0 corresponds to ISO/IEC 10646:2014 plus Amendment 1, plus 41 emoji characters (discussed at the end of this post) that are in Amendment 2.

Unicode 8.0 will see the addition of 7,716 new characters, bringing the total number of graphic and format characters in the Unicode Standard to 120,672 characters in 259 blocks, covering 129 scripts (in case you are concerned that Unicode is running out of space, that still leaves room for another 853,793 characters to be encoded). Of these new characters :

The details of the additions for Unicode 8.0 are provided in the two tables below. For the first time in this series of blog posts I am providing a comprehensive list of source documents relating to the encoding of each character or set of characters. Some people think that all you need to do to get a character encoded is post a suggestion to the Unicode mailing list, or tweet the Unicode Consortium, or create a petition on change.org. The reality is that you have to write a detailed proposal document that will be reviewed by the Unicode Technical Committee and the WG2 committee, and if it is approved by the committees the proposed characters will be put through a series of ISO ballots and voted on by ISO national bodies; and so it usually takes two or three years for a character or set of characters to go from initial proposal to final encoding. In some cases, as can be seen below, it may take considerably longer—the Old Hungarian script has taken 7 years and 54 documents to get encoded; and the sinological middle dot letter has taken 6 years to get encoded, and has been moved on and off ISO ballots like a yo-yo. On the other hand, as is discussed below, some of the emoji symbols added to this version of Unicode have been encoded with unseemly haste, bypassing the normal encoding process.

Optional Discourse on Emoji

If you are a time traveller from Unicode 5.0, nearly ten years ago, when this series of blog posts started, then very little discussed below will be in any way believable, and you may well be tempted to dismiss this post as a feeble April Fool's joke. My advice to time travellers and anyone who still believes that there are principles and procedures for encoding characters in the Unicode Standard is to read no further, and flee this page while you still can.

Well, perhaps that is a bit harsh. Maybe it is more accurate to say that there is now a two-track approach to character encoding: serious scholars such as Michael Everson and Anshuman Pandey (and even myself), who who have dedicated themselves for many years to getting minority and historic scripts encoded, still have to rigorously justify encoding to the committees; but emoji and symbols proposals (I use the term loosely, as such 'proposals' often do not include the mandatory formal proposal summary form) are currently being waved through by the UTC with the minimum of scrutiny.


An Observer's Eye View of the Encoding Process for Symbols

A good example of the way things appear to be going can be seen with the Observer Eye Symbol. This character is not in Unicode 8.0, but was accepted for encoding at the last UTC meeting in February 2015 on the basis that such a symbol could be "useful in illustrating scientific discussions" and "[a]n international symbol for an observer was mentioned and drawn (see below) by Professor Charles Bailyn in Yale University course ASTR-160: Frontiers and Controversies in Astrophysics Lecture 2 - Planetary Orbits". The acceptance of this character goes against several long-standing encoding principles: 1) characters are not encoded simply because someone thinks that they would be useful to have; 2) "the Unicode Standard does not encode idiosyncratic, personal, novel, or private-use characters" [The Unicode Standard chapter 1]; and 3) evidence of textual usage (preferably in printed sources) is required to be provided by the proposer. I believe that it is inconceivable that this encoding rationale and evidence of usage would have been considered sufficient grounds for encoding such a character five years ago.* But now it seems—and it is fair to say that I too am jumping on this band wagon—anything goes when it comes to encoding symbols.


Simon Griffee, International symbol for an observer [L2/15-031]


* The single hand-drawn example of an observer eye symbol in the original proposal has since been supplemented by five examples of drawing "retrieved from a web image search" by Unicode Technical Vice President Rick McGowan (L2/15-095), but there is no context for these images, no references or bibligraphy indicating their sources, and crucially they are are all examples that show the observer eye symbol as part of an illustration, and so do not provide any evidence of the symbol's use in text.


Junk Food and Junk Characters

Up until a few years ago there were relatively few Unicode characters representing particular things (such as snowmen, umbrellas and cups of tea or coffee), and there were fairly strict rules about what symbols are or are not appropriate for encoding in Unicode, and one of the main criteria was that the proposer had to show evidence of usage of the symbol in a plain text context. This all changed with the advent of Unicode 6.0 in October 2010, which (after long and heated debates) included a set of nearly 700 emoji and emoticon symbols that were ostensibly encoded in order to solve interoperability issues between various Japanese mobile phone vendors who used different variants of emoji at different private-use code points. The random and eclectic nature of these symbols meant that it became hard to argue against encoding other similar or analogous symbols representing people or things, and since then the encoding of symbols seems to some to have snowballed out of control. The situation has become worse over the last two or three years with the implementation of colourized emoji and emoticons by major vendors such as Apple, Microsoft, Google and Twitter, and the now widespread use of colourized emoji characters on social media. When twitter users look at the existing emoji characters and see that they include french fries 🍟, hamburgers 🍔 and doughnuts 🍩, but not tacos, paella or fabada, is it any wonder that partisans of these foods feel aggrieved, and demand that they too be included in Unicode ?

Symbols representing people, animals, food & drink, human artefacts and human activities are intrinsically open-ended, and it is hard to see how the line can be drawn without simply refusing to encode any more emoji at all. There has been some attempt to limit the scope of encoding emoji characters (see Unicode Emoji : Selection Factors), but the current strategy seems to be to try to fill in the gaps as much as possible in the hope that people will eventually stop asking for new emoji symbols for their favourite food, drink, animal, dinosaur, sport or religion. It seems unlikely to be a successful strategy.


Unicode 8.0 Emoji Additions

Unicode 8.0 attempts to fill in some of the gaps with ten new emoticon characters and twenty-six emoji characters, mostly relating to food, sports, astrology and religion.*

* A 'Dhyani Buddha' character was also originally proposed for encoding in Unicode 8.0 as a religious symbol representing Buddhism, but in response to public feedback it was removed (see Mark Davis, "Recommended Disposition on Feedback for PRI 286 & related Emoji docs).

This is not a very large number of new characters, but the way in which they came to be added to Unicode 8.0 is very disturbing to me, as someone who is involved in the WG2 side of things. These characters were not proposed for encoding in the normal way, with a proposal document going to the WG2 committee, but thirty-seven characters (the above thirty-six plus the Dhyani Buddha character that was later dropped) were agreed upon by a cabal going under the name of the "Emoji ad-hoc subcommittee", and presented to the UTC at UTC Meeting 141 at the end of October 2014, which accepted them "for encoding in a future version of the standard". This would normally mean that the proposal documents would be submitted to WG2, and they would get encoded in Unicode 9 or 10 after going through the ISO ballot process. However, what actually happened is that on 14 November 2014 the Unicode Consortium announced in a blog post that 37 emoji characters were candidates for inclusion in Unicode 8.0 in June of the following year. This timetable meant that there was no opportunity to put the characters on an ISO ballot for consideration by ISO national bodies before the repertoire of Unicode 8.0 was fixed (a three-month PDAM ballot which included the emoji modifier characters but not the 37 new emoji candidates had been issued just days before the October UTC meeting).

There is precedent for the Unicode Consortium to fast-track urgently-needed characters into the Unicode Standard before the characters have completed the ISO ballot process. This has occured in the past with newly-designed national currency symbols such as the euro sign , the Indian rupee sign , the Turkish lira sign , and the Russian ruble sign , but in these cases the new characters were non-controversial and demonstrably urgently-required. Can it really be argued that the need to have a taco emoji encoded in Unicode is in any way on the same level of urgency as the need for currency symbols which are going to be used by governments and banks ?

When I brought up the question on the (private) UTC mailing list, I was reminded that WG2 had been warned at the WG2 meeting in Colombo, Sri Lanka in September/October 2014 that "additional emoji characters that address user concerns in relation to diversity" may be considered for encoding in the Unicode Standard (see Unicode Liaison Report to SC2). Given the context of this statement, I do not think that I was the only person at the meeting who assumed that it referred to the urgent need to encode racially diverse emoji characters rather than symbols for fast food and sports equipment. The statement in the same document that "In exceptional cases, such as new currency symbols, characters may be added to a given Unicode version that have not yet reached the approval stage in ISO process" would not seem to me to apply to any of the Unicode 8.0 emoji characters. But the the justification given to me on the UTC mailing list for fast-tracking these 37 emoji was that they were urgently required to address a perceived bias towards Western culture in the current set of emoji ... hot dog anyone ?


WG2 Meeting 63, Colombo, Sri Lanka, October 2014 (I'm in there somewhere)


In the end, an additional two-month PDAM ballot was squeezed into the schedule (ballot closing 3 April 2015), with the thirty-seven emoji included, but at this late stage it leaves the ISO national bodies little choice but to accept them as a fait accompli.


Emoji Modifier Characters

Unicode code charts show characters in monochrome, and up until very recently font technology has not supported polychromatic glyphs, so historically the colour of Unicode characters has not been a big issue. However, recent advances in technology has allowed major vendors such as Apple, Microsoft, Google and Twitter to implement multi-coloured versions of some Unicode symbol characters, in particular emoticons and emoji. Colourized emoticons are not a problem as they have generally been implemented as non-realistic yellow faces.


List of emoji characters, with images (4th column shows the Unicode code chart glyphs)


But symbols representing human beings or human body parts have tended to be represented as realistic humans with realistic skin tones, even when the representative glyphs in the Unicode code charts are silhouettes.

List of emoji characters, with images (4th column shows the Unicode code chart glyphs)


As the representative glyphs for people in the Unicode code charts look in many cases as if they represent white people, even in monochrone, and as the earliest implementations of multicoloured glyphs tended to show very pale skin tones, there has been an impression that Unicode is only catering for a certain racial demographic. Over the last year or two there have been widespread calls for the Unicode Consortium to encode racially diverse versions of emoji characters representing humans or human body parts, and under intense pressure from the public, the media, and consortium members such as Apple and Google, the Unicode Technical Committee put forward a set of five emoji skin tone modifier characters as a solution.


Code Point Character Name Glyph Sequence with U+1F466 BOY
Supported Unsupported
U+1F3FB emoji modifier fitzpatrick type-1-2
U+1F3FC emoji modifier fitzpatrick type-3
U+1F3FD emoji modifier fitzpatrick type-4
U+1F3FE emoji modifier fitzpatrick type-5
U+1F3FF emoji modifier fitzpatrick type-6

By themselves these five characters are intended to be displayed as square fragments of colour, but when combined with any of a defined set of Unicode characters representing people or human body parts they should magically change the character's skin tone. See Unicode Technical Report #51 : Unicode Emoji for more details.

The way that these emoji modifier characters act is similar to the way variation selectors work, but there is one crucial difference: variation selectors are default-ignorable non-spacing marks, which means that if a process does not support a particular variation sequence the variation selector may be ignored (not rendered) and the base character of the variation sequence rendered as if the variation selector was not present. In contrast the emoji modifier characters are spacing modifier symbols which should not be ignored: if a process supports a sequence of base character followed by an emoji modifier character then it should render the base character with the appropriate skin tone and discard the emoji modifier character ("Supported" column in above table), but if a process does not support the sequence it should render the base character followed by the emoji modifier character with their respective default glyphs ("Unsupported" column in above table). This way users should realise that they are missing something when they see an unsupported emoji modifier sequence.

This solution may work for Unicode characters showing a single person, but you may wonder how multiracial emoji symbols showing two or more people with different skin tones could be represented. Would there, for example, be a way of specifying that U+1F46A 👪 family should be rendered with mother, father and child with different skin tones? The answer would seem to be no; but the Emoji Ad-hoc Committee has come up with an cunning solution that allows for the combination of emoji characters, emoji modifier characters and zero-width joiner characters to produce arbitrary emoji glyphs, as shown in the example below, where a sequence of eleven Unicode characters would be intended to be rendered as a single colourized glyph showing a multiracial family. A rather inelegant solution, some might think, and more akin to a markup language than plain text.

These emoji skin tone modifier characters are far from non-controversial, and when presented to the WG2 meeting in October 2014, there was considerable debate about whether they are actually needed and whether or not they are the best solution to the problem. Opinion amongst WG2 experts at the meeting ranged from grudging acceptance of them as a political necessity to outright opposition as potentially racist in their own right. Two counter-proposals were put forward by different experts at the meeting :


Neither of these two proposals gained much support, and the five characters emoji modifier characters proposed by the UTC were put in the PDAM 2.2 ballot for ISO/IEC 10646:2014, and accepted by ISO national bodies (see WG2 N4656). The question is, now that there is a mechanism for defining skin tone colours for Unicode characters, will this be enough ? Or will users demand a similar mechanism to specify hair colour and eye colour ? And will users want to expand the concept of modifier characters to cover any colour and any Unicode character ? We shall see ...
