The "Grinning Face" emoji, from the Twemoji set

Emoji being added to a text message, 2013

An emoji ( i-MOH-jee; plural emoji or emojis; Japanese: 絵文字) is a pictogram, logogram, ideogram, or smiley embedded in text and used in electronic messages and web pages. The primary function of emoji is to fill in emotional cues otherwise missing from typed conversation. Emoji exist in various genres, including facial expressions, common objects, places and types of weather, and animals. They are much like emoticons, except emoji are pictures rather than typographic approximations; the term "emoji" in the strict sense refers to such pictures which can be represented as encoded characters, but it is sometimes applied to messaging stickers by extension. Originally meaning pictograph, the word emoji comes from Japanese e (絵, 'picture') + moji (文字, 'character'); the resemblance to the English words emotion and emoticon is purely coincidental. The ISO 15924 script code for emoji is Zsye.

Originating on Japanese mobile phones in 1997, emoji became increasingly popular worldwide in the 2010s after being added to several mobile operating systems. They are now considered to be a large part of popular culture in the West and around the world. In 2015, Oxford Dictionaries named the Face with Tears of Joy emoji (😂) the word of the year.

History

Evolution from emoticons (1990s)

The emoji was predated by the emoticon, a concept implemented in 1982 by computer scientist Scott Fahlman when he suggested text-based symbols such as :-) and :-( could be used to replace language. Theories about language replacement can be traced back to the 1960s, when Russian novelist and professor Vladimir Nabokov stated in an interview with The New York Times: "I often think there should exist a special typographical sign for a smile — some sort of concave mark, a supine round bracket." It did not become a mainstream concept until the 1990s when Japanese, American and European companies began developing Fahlman's idea. Mary Kalantzis and Bill Cope point out that similar symbology was incorporated by Bruce Parello, a student at the University of Illinois, into PLATO IV, the first e-learning system, in 1972. The PLATO system was not considered mainstream, and therefore Parello's pictograms were only used by a small number of people. Scott Fahlman's emoticons importantly used common alphabet symbols, and aimed to replace language/text to express emotion, and for that reason are seen as the actual origin of emoticons.

Wingdings icons, including smiling and frowning faces

Wingdings, a font invented by Charles Bigelow and Kris Holmes, was released by Microsoft in 1990. It could be used to send pictographs in rich text messages, but would only load on devices with the Wingdings font installed. In 1995, the French newspaper Le Monde announced that Alcatel would be launching a new phone, the BC 600. Its welcome screen displayed a digital smiley face, replacing the usual text seen as part of the "welcome message" often seen on other devices at the time. In 1997, J-Phone launched the SkyWalker DP-211SW, which contained a set of 90 emoji. It is thought to be the first set of its kind. Its designs, each measuring 12 by 12 pixels were monochrome, depicting numbers, sports, the time, moon phases and the weather. It contained the Pile of Poo emoji in particular. The J-Phone model experienced low sales, and the emoji set was thus rarely used.

In 1999, Shigetaka Kurita created 176 emoji as part of NTT DoCoMo's i-mode, used on its mobile platform. They were intended to help facilitate electronic communication, and to serve as a distinguishing feature from other services. Due to their influence, Kurita's designs were once claimed to be the first cellular emoji; however, Kurita has denied that this is the case. According to interviews, he took inspiration from Japanese manga where characters are often drawn with symbolic representations called manpu (such as a water drop on a face representing nervousness or confusion), and weather pictograms used to depict the weather conditions at any given time. He also drew inspiration from Chinese characters and street sign pictograms. The DoCoMo i-Mode set included facial expressions, such as smiley faces, derived from a Japanese visual style commonly found in manga and anime, combined with kaomoji and smiley elements. Kurita's work is displayed in the Museum of Modern Art in New York City.

Kurita's emoji were brightly colored, albeit with a single color per glyph. General-use emoji, such as sports, actions and weather, can readily be traced back to Kurita's emoji set. Notably absent from the set were pictograms that demonstrated emotion. The yellow-faced emoji in current use evolved from other emoticon sets and cannot be traced back to Kurita's work. His set also had generic images much like the J-Phones. Elsewhere in the 1990s, Nokia phones began including preset pictograms in its text messaging app, which they defined as "smileys and symbols". A third notable emoji set was introduced by Japanese mobile phone brand au by KDDI.

Development of emoji sets (2000–2007)

The basic 12-by-12-pixel emoji in Japan grew in popularity across various platforms over the next decade. This was aided by the popularity of DoCoMo i-mode, which for many was the origins of the smartphone. The i-mode service also saw the introduction of emoji in conversation form on messenger apps. By 2004, i-mode had 40 million subscribers, exposing numerous people to emoji for the first time between 2000 and 2004. The popularity of i-mode led to other manufacturers offering their own emoji sets. While emoji adoption was high in Japan during this time, the competitors failed to collaborate to create a uniform set of emoji to be used across all platforms in the country.

Smiley faces from DOS code page 437

The Universal Coded Character Set (Unicode), controlled by the Unicode Consortium and ISO/IEC JTC 1/SC 2, had already been established as the international standard for text representation (ISO/IEC 10646) since 1993, although variants of Shift JIS remained relatively common in Japan. Unicode included several characters which would subsequently be classified as emoji, including some from North American or Western European sources such as DOS code page 437, ITC Zapf Dingbats or the WordPerfect Iconic Symbols set. Unicode coverage of written characters was extended several times by new editions during the 2000s, with little interest in incorporating the Japanese cellular emoji sets (deemed out of scope), although symbol characters which would subsequently be classified as emoji continued to be added. For example, Unicode 4.0 contained 16 new emoji, which included direction arrows, a warning triangle, and an eject button. Besides Zapf Dingbats, other dingbat fonts such as Wingdings or Webdings also included additional pictographic symbols in their own custom pi font encodings; unlike Zapf Dingbats, however, many of these would not be available as Unicode emoji until 2014.

Nicolas Loufrani applied to the US Copyright Office in 1999 to register the 471 smileys that he created. Soon after he created The Smiley Dictionary, which not only hosted the largest number of smileys at the time, it also categorized them. The desktop platform was aimed at allowing people to insert smileys as text when sending emails and writing on a desktop computer. By 2003, it had grown to 887 smileys and 640 ascii emotions.

The smiley toolbar offered a variety of symbols and smileys and was used on platforms such as MSN Messenger. Nokia, then one of the largest global telecom companies, was still referring to today's emoji sets as smileys in 2001. The digital smiley movement was headed up by Nicolas Loufrani, the CEO of The Smiley Company. He created a smiley toolbar, which was available at smileydictionary.com during the early 2000s to be sent as emoji are today.

Over the next two years, The Smiley Dictionary became the plug-in of choice for forums and online instant messaging platforms. There were competitors, but The Smiley Dictionary was by far the most popular. Platforms such as MSN Messenger allowed for customisation from 2001 onwards, with many users importing emoticons to use in messages as text. These emoticons would eventually go on to become the modern day emoji. It was not until MSN Messenger and BlackBerry noticed the popularity of these unofficial sets and launched their own from late 2003 onwards.

Beginnings of Unicode emoji (2007–2014)

The first American company to take emojis seriously was Google beginning in 2007. In August 2007, a team made up of Mark Davis and his colleagues Kat Momoi and Markus Scherer began petitioning to Unicode Technical Committee (UTC) in an attempt standardise the emoji. The UTC, having previously deemed emoji to be out of scope for Unicode, made the decision to broaden its scope to enable compatibility with the Japanese cellular carrier formats which were becoming more widespread. Peter Edberg and Yasuo Kida joined the collaborative effort from Apple Inc. shortly after, and their official UTC proposal came in January 2009 with 625 new emoji characters. Unicode accepted the proposal in 2010.

Pending the assignment of standard Unicode code points, Google and Apple implemented emoji support via Private Use Area schemes. Google first introduced emoji in Gmail in October 2008, in collaboration with au by KDDI, and Apple introduced the first release of Apple Color Emoji to iPhone OS on 21 November 2008. Initially, Apple's emoji support was implemented for holders of a SoftBank SIM card; the emoji themselves were represented using SoftBank's Private Use Area scheme and mostly resembled the SoftBank designs. Gmail emoji used their own Private Use Area scheme, in a supplementary Private Use plane.

Separately, a proposal had been submitted in 2008 to add the ARIB extended characters used in broadcasting in Japan to Unicode. This included several pictographic symbols. These were added in Unicode 5.2 in 2009, a year before the cellular emoji sets were fully added; they include several characters which either also appeared amongst the cellular emoji or were subsequently classified as emoji.

After iPhone users in the United States discovered that downloading Japanese apps allowed access to the keyboard, pressure grew to expand the availability of the emoji keyboard beyond Japan. The Emoji application for iOS, which altered the Settings app to allow access to the emoji keyboard, was created by Josh Gare in February 2010. Before the existence of Gare's Emoji app, Apple had intended for the emoji keyboard to only be available in Japan in iOS version 2.2.

Throughout 2009, members of the Unicode Consortium and national standardization bodies of various countries gave feedback and proposed changes to the international standardization of the emoji. The feedback from various bodies in the United States, Europe, and Japan agreed on a set of 722 emoji as the standard set. This would be released in October 2010 in Unicode 6.0. Apple made the emoji keyboard available to those outside of Japan in iOS version 5.0 in 2011. Later, Unicode 7.0 (June 2014) added the character repertoires of the Webdings and Wingdings fonts to Unicode, resulting in approximately 250 more Unicode emoji.

The Unicode emoji whose code points were assigned in 2014 or earlier are therefore taken from several sources. A single character could exist in multiple sources, and characters from a source were unified with existing characters where appropriate: for example, the "shower" weather symbol (☔️) from the ARIB source was unified with an existing umbrella with raindrops character, which had been added for KPS 9566 compatibility. The emoji characters named "Rain" ("雨", ame) from all three Japanese carriers were in turn unified with the ARIB character. However, the Unicode Consortium groups the most significant sources of emoji into four categories:

UTS #51 and modern emoji (2015–present)

Color emoji from Google's Noto Emoji Project, started in 2012 and used by Gmail, Google Hangouts, ChromeOS and Android

In late 2014, a Public Review Issue was created by the Unicode Technical Committee, seeking feedback on a proposed Unicode Technical Report (UTR) titled "Unicode Emoji". This was intended to improve interoperability of emoji between vendors, and define a means of supporting multiple skin tones. The feedback period closed in January 2015. Also in January 2015, the use of the zero width joiner to indicate that a sequence of emoji could be shown as a single equivalent glyph (analogous to a ligature) as a means of implementing emoji without atomic code points, such as varied compositions of families, was discussed within the "emoji ad-hoc committee".

Unicode 8.0 (June 2015) added another 41 emoji, including articles of sports equipment such as the cricket bat, food items such as the taco, new facial expressions, and symbols for places of worship, as well as five characters (crab, scorpion, lion face, bow and arrow, amphora) to improve support for pictorial rather than symbolic representations of the signs of the Zodiac.

Also in June 2015, the first approved version ("Emoji 1.0") of the Unicode Emoji report was published as Unicode Technical Report #51 (UTR #51). This introduced the mechanism of skin tone indicators, the first official recommendations about which Unicode characters were to be considered emoji, and the first official recommendations about which characters were to be displayed in an emoji font in absence of a variation selector, and listed the zero width joiner sequences for families and couples that were implemented by existing vendors. Maintenance of UTR #51, taking emoji requests, and creating proposals for emoji characters and emoji mechanisms was made the responsibility of the Unicode Emoji Subcommittee (ESC), operating as a subcommittee of the Unicode Technical Committee,

With the release of version 5.0 in May 2017 alongside Unicode 10.0, UTR #51 was redesignated a Unicode Technical Standard (UTS #51), making it an independent specification rather than merely an informative document. As of July 2017^[update] there were 2,666 Unicode emoji listed. The next version of UTS #51 (published in May 2018) skipped to the version number Emoji 11.0, so as to synchronise its major version number with the corresponding version of the Unicode Standard.

The popularity of emoji has caused pressure from vendors and international markets to add additional designs into the Unicode standard to meet the demands of different cultures. Some characters now defined as emoji are inherited from a variety of pre-Unicode messenger systems not only used in Japan, including Yahoo and MSN Messenger.

Corporate demand for emoji standardization has placed pressures on the Unicode Consortium, with some members complaining that it had overtaken the group's traditional focus on standardizing characters used for minority languages and transcribing historical records. Conversely, the Consortium recognises that public desire for emoji support has put pressure on vendors to improve their Unicode support, which is especially true for characters outside the Basic Multilingual Plane, thus leading to better support for Unicode's historic and minority scripts in deployed software.

Linguistic function of emojis

Linguistically, emoji are used to indicate emotional state, they tend to be used more in positive communication. Some researchers believe emoji can be used for visual rhetoric. Emoji can be used to set emotional tone in messages. Emoji tend not to have their own meaning but act as a paralanguage adding meaning to text. Emoji can add clarity and credibility to text.

Sociolinguistically, the use of emoji differ depending on speaker and setting. Women use emoji more than men. Men use a wider variety of emoji. Women are more likely to use emoji in public communication than private communication. Extraversion and agreeableness are positively correlated with emoji use, neuroticism is negative correlated. Emoji use differ between cultures: studies in terms of Hofstede's cultural dimensions theory found that cultures with high power distance and tolerance to indulgence used more negative emojis, while those with high uncertainty avoidance, individualism, and long-term orientation use more positive emojis.

Emoji communication problems

Research has shown that emoji are often misunderstood. In some cases, this misunderstanding is related to how the actual emoji design is interpreted by the viewer; in other cases, the emoji that was sent is not shown in the same way on the receiving side.

The first issue relates to the cultural or contextual interpretation of the emoji. When the author picks an emoji, they think about it in a certain way, but the same character may not trigger the same thoughts in the mind of the receiver (see also Models of communication).

For example, people in China have developed a system for using emoji subversively, so that a smiley face could be sent to convey a despising, mocking, and even obnoxious attitude, as the orbicularis oculi (the muscle near that upper eye corner) on the face of the emoji does not move, and the orbicularis oris (the one near the mouth) tightens, which is believed to be a sign of suppressing a smile.

The second problem relates to technology and branding. When an author of a message picks an emoji from a list, it is normally encoded in a non-graphical manner during the transmission, and if the author and the reader do not use the same software or operating system for their devices, the reader's device may visualize the same emoji in a different way. Small changes to a character's look may completely alter its perceived meaning with the receiver. As an example, in April 2020, British actress and presenter Jameela Jamil posted a tweet from her iPhone using the Face with Hand Over Mouth emoji (🤭) as part of a comment on people shopping for food during the COVID-19 pandemic. On Apple's iOS, the emoji expression is neutral and pensive, but on other platforms the emoji shows as a giggling face. Many fans were initially upset thinking that she, as a well off celebrity, was mocking poor people, but this was not her intended meaning.

Researchers from German Studies Institute at Ruhr-Universität Bochum found that most people can easily understand an emoji when it replaces a word directly – like an icon for a rose instead of the word 'rose' – yet it takes people about 50 percent longer to comprehend the emoji.

Variation and ambiguity

Emoji characters vary slightly between platforms within the limits in meaning defined by the Unicode specification, as companies have tried to provide artistic presentations of ideas and objects. For example, following an Apple tradition, the calendar emoji on Apple products always shows July 17, the date in 2002 Apple announced its iCal calendar application for macOS. This led some Apple product users to initially nickname July 17 "World Emoji Day". Other emoji fonts show different dates or do not show a specific one.

Emoji implementation

Early implementation in Japan

Various, often incompatible, character encoding schemes were developed by the different mobile providers in Japan for their own emoji sets. For example, the extended Shift JIS representation F797 is used for a convenience store (🏪) by SoftBank, but for a wristwatch (⌚️) by KDDI. All three vendors also developed schemes for encoding their emoji in the Unicode Private Use Area: DoCoMo, for example, used the range U+E63E through U+E757. Versions of iOS prior to 5.1 encoded emoji in the SoftBank private use area.

Unicode support considerations

Most, but not all, emoji are included in the Supplementary Multilingual Plane (SMP) of Unicode, which is also used for ancient scripts, some modern scripts such as Adlam or Osage, and special-use characters such as Mathematical Alphanumeric Symbols. Some systems introduced prior to the advent of Unicode emoji were only designed to support characters in the Basic Multilingual Plane (BMP), on the assumption that non-BMP characters would rarely be encountered, although failure to properly handle characters outside of the BMP precludes Unicode compliance.

The introduction of Unicode emoji created an incentive for vendors to improve their support for non-BMP characters. The Unicode Consortium notes that "[b]ecause of the demand for emoji, many implementations have upgraded their Unicode support substantially", also helping support for minority languages that use those features.

Color support

Any operating system that supports adding additional fonts to the system can add an emoji-supporting font. However, inclusion of colorful emoji in existing font formats requires dedicated support for color glyphs. Not all operating systems have support for color fonts, so in these cases emoji might have to be rendered as black-and-white line art or not at all. There are four different formats used for multi-color glyphs in an SFNT font, not all of which are necessarily supported by a given operating system library or software package such as a web browser or graphical program. This means that color fonts may need to be supplied in several formats to be usable on multiple operating systems, or in multiple applications.

Implementation by different platforms and vendors

Apple first introduced emoji to their desktop operating system with the release of OS X 10.7 Lion, in 2011. Users can view emoji characters sent through email and messaging applications, which are commonly shared by mobile users, as well as any other application. Users can create emoji symbols using the "Characters" special input panel from almost any native application by selecting the "Edit" menu and pulling down to "Special Characters", or by the key combination Command. The emoji keyboard was first available in Japan with the release of iPhone OS version 2.2 in 2008. The emoji keyboard was not officially made available outside of Japan until iOS version 5.0. From iPhone OS 2.2 through to iOS 4.3.5 (2011), those outside Japan could access the keyboard but had to use a third-party app to enable it. Apple has revealed that the "face with tears of joy" is the most popular emoji among English-speaking Americans. On second place is the "heart" emoji, followed by the "Loudly Crying Face".

An update for Windows 7 and Windows Server 2008 R2 brought a subset of the monochrome Unicode set to those operating systems as part of the Segoe UI Symbol font. As of Windows 8.1 Preview, the Segoe UI Emoji font is included, which supplies full-color pictographs. The plain Segoe UI font lacks emoji characters, whereas Segoe UI Symbol and Segoe UI Emoji include them. Emoji characters are accessed through the onscreen keyboard's 😀 key, or through the physical keyboard shortcut Win.

In 2016, Firefox 50 added in-browser emoji rendering for platforms lacking in native support.

Facebook and Twitter replace all Unicode emoji used on their websites with their own custom graphics. Prior to October 2017, Facebook had different sets for the main site and for its Messenger service, where only the former provides complete coverage. Messenger now uses Apple emoji on iOS, and the main Facebook set elsewhere. Facebook reactions are only partially compatible with standard emoji.

Modifiers

Emoji versus text presentation

Unicode defines variation sequences for many of its emoji to indicate their desired presentation.

Emoji characters can have two main kinds of presentation:

• an emoji presentation, with colorful and perhaps whimsical shapes, even animated
  
• a text presentation, such as black & white

Specifying the desired presentation is done by following the base emoji with either U+FE0E VARIATION SELECTOR-15 (VS15) for text or U+FE0F VARIATION SELECTOR-16 (VS16) for emoji-style.

Sample emoji variation sequences

U+	2139	231B	26A0	2712	2764	1F004	1F21A
default presentation	text	emoji	text	text	text	emoji	emoji
base code point	ℹ	⌛	⚠	✒	❤	🀄	🈚
base+VS15 (text)	ℹ︎	⌛︎	⚠︎	✒︎	❤︎	🀄︎	🈚︎
base+VS16 (emoji)	ℹ️	⌛️	⚠️	✒️	❤️	🀄️	🈚️
Twemoji image

As of version 15 (2022), Unicode defines presentation sequences for 354 characters.

Skin color

Five symbol modifier characters were added with Unicode 8.0 to provide a range of skin tones for human emoji. These modifiers are called EMOJI MODIFIER FITZPATRICK TYPE-1-2, -3, -4, -5, and -6 (U+1F3FB–U+1F3FF): 🏻 🏼 🏽 🏾 🏿. They are based on the Fitzpatrick scale for classifying human skin color. Human emoji that are not followed by one of these five modifiers should be displayed in a generic, non-realistic skin tone, such as bright yellow (■), blue (■), or gray (■).

The following table shows both the Unicode characters and the open-source "Twemoji" images, designed by Twitter:

In Unicode

Unicode 15.0 specifies a total of 3,664 emoji using 1,424 characters spread across 24 blocks, of which 26 are Regional indicator symbols that combine in pairs to form flag emoji, and 12 (#, * and 0–9) are base characters for keycap emoji sequences:

637 of the 768 code points in the Miscellaneous Symbols and Pictographs block are considered emoji. 242 of the 256 code points in the Supplemental Symbols and Pictographs block are considered emoji. All of the 107 code points in the Symbols and Pictographs Extended-A block are considered emoji. All of the 80 code points in the Emoticons block are considered emoji. 105 of the 118 code points in the Transport and Map Symbols block are considered emoji. 83 of the 256 code points in the Miscellaneous Symbols block are considered emoji. 33 of the 192 code points in the Dingbats block are considered emoji.

Additional emoji can be found in the following Unicode blocks: Arrows (8 code points considered emoji), Basic Latin (12), CJK Symbols and Punctuation (2), Enclosed Alphanumeric Supplement (41), Enclosed Alphanumerics (1), Enclosed CJK Letters and Months (2), Enclosed Ideographic Supplement (15), General Punctuation (2), Geometric Shapes (8), Geometric Shapes Extended (13), Latin-1 Supplement (2), Letterlike Symbols (2), Mahjong Tiles (1), Miscellaneous Symbols and Arrows (7), Miscellaneous Technical (18), Playing Cards (1), and Supplemental Arrows-B (2).
