In internationalization , CJK characters is a collective term for graphemes used in the Chinese , Japanese , and Korean writing systems , which each include Chinese characters . It can also go by CJKV to include Chữ Nôm , the Chinese-origin logographic script formerly used for the Vietnamese language , or CJKVZ to also include Sawndip , used to write the Zhuang languages .

54-810: Standard Mandarin Chinese and Standard Cantonese are written almost exclusively in Chinese characters. Over 3,000 characters are required for general literacy , with up to 40,000 characters for reasonably complete coverage. Japanese uses fewer characters—general literacy in Japanese can be expected with 2,136 characters. The use of Chinese characters in Korea is increasingly rare, although idiosyncratic use of Chinese characters in proper names requires knowledge (and therefore availability) of many more characters. Even today, however, South Korean students are taught 1,800 characters . Other scripts used for these languages, such as bopomofo and

108-568: A 16-bit fixed width encoding or multi-byte variable-length encodings. The 16-bit fixed width encodings, such as those from Unicode up to and including version 2.0, are now deprecated due to the requirement to encode more characters than a 16-bit encoding can accommodate—Unicode 5.0 has some 70,000 Han characters—and the requirement by the Chinese government that software in China support the GB 18030 character set. Although CJK encodings have common character sets,

162-729: A particular social context (even if that context is "school"), and, after print acquisition, every instance of reading or writing will be for a specific purpose and occasion with particular readers and writers in mind. Reading and writing, therefore, are never separable from social and cultural elements. A corollary point made by David Barton and Rosalind Ivanić , among others, is that the cognitive and societal effects of acquiring literacy are not easily predictable, since, as Brian Street has argued, "the ways in which people address reading and writing are themselves rooted in conceptions of knowledge, identity, and being." Consequently, as Jack Goody has documented, historically, literacy has included

216-407: A precursor to early cuneiform writing once people began recording information on clay tablets. Proto-Cuneiform texts exhibit not only numerical signs but also ideograms depicting objects being counted. Though the traditional view had been that cuneiform literacy was restricted to a class of scribes, assyriologists including Claus Wilcke and Dominique Charpin have argued that functional literacy

270-621: A resurgence as a result, and by the 15th century, paper was widespread. The Reformation stressed the importance of literacy and being able to read the Bible. The Protestant countries were the first to attain full literacy. In a more secular context, inspired by the Enlightenment , Sweden implemented programs in 1723 aimed at making the population fully literate. Other countries implemented similar measures at this time. These included Denmark in 1739, Poland in 1783, and France in 1794/5. Literacy

324-591: Is a Unicode block containing rare and historic CJK Unified Ideographs for Chinese, Japanese, Korean, and Vietnamese which were submitted to the Ideographic Research Group during 2015. It is the first block to be allocated to the Tertiary Ideographic Plane . The exotic characters 𰻞 biáng and 𱁬 taito are present in this block. The following Unicode-related documents record the purpose and process of defining specific characters in

378-453: Is also gaining momentum. The traditional concept of literacy widened as a consensus emerged among researchers in composition studies , education research , and anthropological linguistics that it makes little sense to speak of reading or writing outside of a specific context, with linguist James Paul Gee describing it as "simply incoherent." For example, even the extremely early stages of acquiring mastery over symbol shapes take place in

432-482: Is concentrated among younger people," along with increased rates among rural populations and women. This evidence indicates that illiteracy is a complex phenomenon with multiple factors impacting rates of illiteracy and the type of illiteracy one may experience. Literacy has rapidly spread in several regions in the last twenty-five years, and the United Nations's global initiative with Sustainable Development Goal 4

486-593: Is more consistent with an early form of Canaanite that was used c.  1100 BCE . While the earliest Greek inscriptions are dated circa 8th century BCE, epigraphical comparisons to Proto-Canaanite suggest that the Greeks may have adopted the consonantal alphabet as early as 1100 BCE and later "added in five characters to represent vowels". Phoenician, which is considered to contain the first linear alphabet, rapidly spread to Mediterranean port cities in northern Canaan. Some archeologists believe that Phoenician influenced

540-435: Is part of spatial, audio, and visual patterns (Rhodes & Robnolt, 2009)". Objections have been raised that this concept downplays the importance of reading instruction that focuses on "alphabetic representations". However, these are not mutually exclusive , as children can become proficient in word-reading while engaging with multiliteracies. Word reading is fundamental for multiple forms of communication. Beginning in

594-545: Is the ability to read and write. Some researchers suggest that the study of "literacy" as a concept can be divided into two periods: the period before 1950, when literacy was understood solely as alphabetical literacy (word and letter recognition); and the period after 1950, when literacy slowly began to be considered as a wider concept and process, including the social and cultural aspects of reading and writing and functional literacy . The range of definitions of literacy used by NGOs , think tanks , and advocacy groups since

648-510: The Harappa culture. Existing evidence suggests that most early acts of literacy were, in some areas (such as Egypt), closely tied to power and chiefly used for management practices, and probably less than 1% of the population was literate, as it was confined to a very small group. Scholarship by others, such as Dominique Charpin and a project from the European Union , however, suggest that this

702-643: The Latin -based pinyin for Chinese, hiragana and katakana for Japanese, and hangul for Korean, are not strictly "CJK characters", although CJK character sets almost invariably include them as necessary for full coverage of the target languages. The sinologist Carl Leban (1971) produced an early survey of CJK encoding systems. Until the early 20th century, Classical Chinese was the written language of government and scholarship in Vietnam. Popular literature in Vietnamese

756-441: The ancient Semitic-speaking peoples of northern Canaan invented the consonantal alphabet as early as 1500 BCE. Much of this theory's development is credited to English archeologist Flinders Petrie , who, in 1905, came across a series of Canaanite inscriptions in the turquoise mines of Serabit el-Khadem . Ten years later, English Egyptologist Alan Gardiner reasoned that these letters contain an alphabet as well as references to

810-460: The 1940s, the term literacy has often been used to mean having knowledge or skill in a particular field, such as: Functional illiteracy relates to adults and has been defined in different ways: Functional illiteracy is distinguished from primary illiteracy (i.e., the inability to read and write a short, simple statement concerning one's own everyday life) and learning difficulties (e.g., dyslexia ). These categories have been contested—as has

864-570: The 1990s suggests that this shift in understanding from "discrete skill" to "social practice" is both ongoing and uneven. Some definitions remain fairly closely aligned with the traditional "ability to read and write" connotation, whereas others take a broader view: The concept of multiliteracies has gained currency, particularly in English Language Arts curricula, on the grounds that reading "is interactive and informative, and occurs in ever-increasingly technological settings where information

918-565: The 4th and 5th centuries, the Church made efforts to ensure a better clergy, especially the bishops, who were expected to have a classical education—the hallmark of a socially acceptable person in higher society. Even after the remnants of the Western Roman Empire fell in the 470s, literacy continued to be a distinguishing mark of the elite, as communication skills were still important in political and church life (bishops were largely drawn from

972-463: The Apostles' epistles or some other part of Scripture. And if he is illiterate he shall go at the first, third and sixth hours to someone who can teach and has been appointed for him. He shall stand before him and learn very studiously and with all gratitude. The fundamentals of a syllable, the verbs and nouns shall all be written for him and even if he does not want to he shall be compelled to read. During

1026-462: The Canaanite goddess Asherah . In 1948, William F. Albright deciphered the text using new evidence, including a series of inscriptions from Ugarit . Discovered in 1929 by French archaeologist Claude F. A. Schaeffer , some of these inscriptions were mythological texts (written in an early Canaanite dialect) that consisted of a 30-letter cuneiform consonantal alphabet. Another significant discovery

1080-587: The Hebrew and Aramaic alphabets, as these languages evolved during the same time period, share similar features, and are commonly categorized into the same language group. When the Israelites migrated to Canaan between 1200 and 1000 BCE, they adopted a variation of the Canaanite alphabet. Baruch ben Neriah , Jeremiah's scribe, used this alphabet to create the later scripts of the Old Testament . The early Hebrew alphabet

1134-737: The Kingdom of Nabataea, then to the Sinai and Arabian peninsulas, eventually making its way to Africa; and east, where it later influenced the development of the Brahmi script in India. Over the next few centuries, Imperial Aramaic script in Persia evolved into Pahlavi , "as well as for a range of alphabets used by early Turkish and Mongol tribes in Siberia , Mongolia and Turkestan ". During this period, literacy spread among

1188-701: The Late Bronze Age , successor alphabets appeared throughout the Mediterranean region and were used in Phoenician , Hebrew , and Aramaic . According to Goody, these cuneiform scripts may have influenced the development of the Greek alphabet several centuries later. Historically, the Greeks contended that their writing system was modeled after the Phoenicians. However, many Semitic scholars now believe that Ancient Greek

1242-758: The Pacific , as well as Latin America and the Caribbean , have adult literacy rates over 90%. In other regions, illiteracy persists at higher rates; as of 2013, the adult literacy rate in South Asia and North Africa was 67.55% and 59.76% in Sub-Saharan Africa . In much of the world, high youth literacy rates suggest that illiteracy will become less common as more educated younger generations replace less educated older ones. However, in sub-Saharan Africa and South Asia, where

1296-468: The actions and judgments of government officials. Indus script is largely pictorial and has not yet been deciphered; as such, it is unknown whether it includes abstract signs. It is thought that they wrote from right to left and that the script is logographic . Because it has not been deciphered, linguists disagree on whether it is a complete and independent writing system; however, it is generally thought to be an independent writing system that emerged in

1350-429: The ancient Sumerians invented writing . During this era, literacy was "a largely functional matter, propelled by the need to manage the new quantities of information and the new type of governance created by trade and large scale production". Early writing systems first emerged as a recording system in which people used tokens with impressed markings to manage trade and agricultural production. The token system served as

1404-648: The benefits of literacy, some recent literature in economics, starting with the work of Kaushik Basu and James Foster, distinguishes between a "proximate illiterate" and an "isolated illiterate". A "proximate illiterate" lives in a household with literate members, while an "isolated illiterate" lives in a household where everyone is illiterate. Isolated illiteracy is more common among older populations in wealthier nations, where people are less likely to live in multigenerational households with potentially literate relatives. A 2018/2019 UNESCO report noted that "conversely, in low and lower middle income countries, isolated illiteracy

1458-508: The book and the register" and that "no one, either free or slave, could afford to be illiterate". Similarly, Dupont points out, "The written word was all around them, in both public and private life: laws, calendars, regulations at shrines, and funeral epitaphs were engraved in stone or bronze. The Republic amassed huge archives of reports on every aspect of public life." The imperial civilian administration produced masses of documentation used in judicial, fiscal, and administrative matters, as did

1512-623: The bulk of the assigned Unicode code space. There is much controversy among Japanese experts of Chinese characters about the desirability and technical merit of the Han unification process used to map multiple Chinese and Japanese character sets into a single set of unified characters. All three languages can be written both left-to-right and top-to-bottom (right-to-left and top-to-bottom in ancient documents), but are usually considered left-to-right scripts when discussing encoding issues. Libraries cooperated on encoding standards for JACKPHY characters in

1566-705: The common people, both in town and country, are equally intense in their admiration. Frequently, have we seen the butcher-boy, with his tray on his shoulder, reading with the greatest avidity the last "Pickwick"; the footman (whose fopperies are so inimitably laid bare), the maidservant, the chimney sweep, all classes, in fact, read "Boz". From the mid-19th century onward, the Second Industrial Revolution saw technological improvements in paper production. The new distribution networks, enabled by improved roads and rail, resulted in an increased capacity to supply printed material. Social and educational changes increased

1620-466: The competition of the world. In the late 19th century, gas and electric lighting were becoming more common in private homes, replacing candlelight and oil lamps, enabling reading after dark and increasing the appeal of literacy. Data published by UNESCO shows that the worldwide literacy rate among adults has increased, on average, by 5 percentage points every decade since 1950, from 55.7% in 1950 to 86.2% in 2015. Due to rapid population growth , while

1674-555: The concept of "illiteracy" itself—for being predicated on narrow assumptions, primarily derived from school-based contexts, about what counts as reading and writing (e.g., comprehending and following instructions). Script is thought to have developed independently at least five times in human history: in Mesopotamia , Egypt , the Indus civilization , lowland Mesoamerica , and China . Between 3500 BCE and 3000 BCE, in southern Mesopotamia,

1728-525: The demand for reading matter, as rising literacy rates, particularly among the middle and working classes, created a new mass market for printed material. Wider schooling helped increase literacy rates, which in turn helped lower the cost of publication. Unskilled labor forces were common in Western Europe, and, as British industry improved, more engineers and skilled workers who could handle technical instructions and complex situations were needed. Literacy

1836-629: The elite. These oracle-bone inscriptions were the early ancestors of modern Chinese script and contained logosyllabic script and numerals. By the time of the consolidation of the Chinese Empire during the Qin and Han dynasties ( c.  200 BCE ), written documents were central to the formation and policing of a hierarchical bureaucratic governance structure reinforced through law. Within this legal order, written records kept track of and controlled citizen movements, created records of misdeeds, and documented

1890-519: The encodings often used to represent them have been developed separately by different East Asian governments and software companies, and are mutually incompatible. Unicode has attempted, with some controversy, to unify the character sets in a process known as Han unification . CJK character encodings should consist minimally of Han characters plus language-specific phonetic scripts such as pinyin , bopomofo , hiragana, katakana and hangul. CJK character encodings include: The CJK character sets take up

1944-461: The first alphabetic system ( c.  750 BCE ) that used distinctive signs for consonants and vowels. Goody contests: The importance of Greek culture of the subsequent history of Western Europe has led to an over-emphasis, by classicists and others, on the addition of specific vowel signs to the set of consonantal ones that had been developed earlier in Western Asia. Many scholars argue that

1998-497: The lack of a suitable writing medium, as when the Western Roman Empire collapsed, the import of papyrus to Europe ceased. Since papyrus perishes easily and does not last well in the wetter European climate, parchment was used, which was expensive and accessible only by the church and the wealthy. Paper was introduced into Europe via Spain in the 11th century and spread north slowly over the next four centuries. Literacy saw

2052-420: The merchant classes, and 15-20% of the total population may have been literate. The Aramaic language declined with the spread of Islam , which was accompanied by the spread of Arabic . Until recently, it was thought that the majority of people were illiterate in the classical world, though recent work challenges this perception. Anthony DiRenzo asserts that Roman society was "a civilization based on

2106-488: The municipalities. The army kept extensive records relating to supply and duty rosters and submitted reports. Merchants, shippers, and landowners (and their personal staffs), especially of the larger enterprises, must have been literate. In the late fourth century, the Desert Father Pachomius would expect the literacy of a candidate for admission to his monasteries: They shall give him twenty Psalms or two of

2160-747: The percentage of adults who were illiterate decreased, the actual number of illiterate adults increased from 700 million in 1950 to 878 million in 1990, before starting to decrease and falling to 745 million by 2015. The number of illiterate adults remains higher than in 1950, "despite decades of universal education policies, literacy interventions and the spread of print material and information and communications technology (ICT)". Available global data indicates significant variations in literacy rates between world regions. North America, Europe, West Asia , and Central Asia have almost achieved full literacy for men and women aged 15 or older. Most countries in East Asia and

2214-526: The senatorial class) in a new cultural synthesis that made "Christianity the Roman religion". However, these skills were less needed in the absence of a large imperial administrative apparatus whose middle and top echelons were dominated by the elite. Even so, in pre-modern times, it is unlikely that literacy was found in more than about 30–40% of the population. During the Dark Ages , the highest percentage of literacy

2268-737: The seventh century BCE. In the Near East , it was common to record events on clay using the cuneiform script; however, writing Aramaic on leather parchments became common during the Neo-Assyrian empire. With the rise of the Persians in the 5th century BCE, Achaemenid rulers adopted Aramaic as the "diplomatic language". Darius the Great standardized Aramaic, which became the Imperial Aramaic script. This Imperial Aramaic alphabet rapidly spread: west, to

2322-471: The transformation of social systems that rely on literacy and the changing uses of literacy within those evolving systems. According to 2015 data collected by the UNESCO Institute for Statistics , about two-thirds (63%) of the world's illiterate adults are women. This disparity was even starker in previous decades, and from 1970 to 2000, the global gender gap in literacy decreased significantly. Around

2376-471: The vast majority of the world's illiterate youth live, lower school enrollment implies that illiteracy will persist to a greater degree. According to 2013 data, the youth literacy rate (ages 15 to 24) is 84% in South Asia and North Africa and 70% in sub-Saharan Africa. However, the distinction between literacy and illiteracy is not clear-cut. Given that having a literate person in the household confers many of

2430-765: The year 2013, however, this progress stagnated, with the gender gap holding almost constant over the last two decades. In general, the gender gap in literacy was not as pronounced as the regional gap; that is, differences between countries were often larger than gender differences within countries. Sub-Saharan Africa has the lowest overall literacy rate and the widest gender gap: 52% of adult women and 68% of adult men are literate. A similar gender disparity exists in North Africa , where 70% of adult women are literate versus 86% of adult men. In South Asia, 58% of adult women and 77% of adult men are literate.

It is of no use trying to give technical teaching to our citizens without elementary education; uneducated labourers—and many of our labourers are utterly uneducated—are, for the most part, unskilled labourers, and if we leave our work–folk any longer unskilled, notwithstanding their strong sinews and determined energy, they will become overmatched in

2538-544: Was first used by the Olmec and Zapotec civilizations in 900–400 BCE. These civilizations used glyphic writing and bar-and-dot numerical notation systems for purposes related to royal iconography and calendar systems. The earliest written notations in China date back to the Shang dynasty in 1200 BCE. These systematic notations, inscribed on bones, recorded sacrifices made, tributes received, and animals hunted, which were activities of

2592-466: Was found among the clergy and monks, as they made up much of the staff needed to administer the states of western Europe. An abundance of graffiti written in the Nabataean script dating back to the beginning of the first millennium CE has been taken to imply a relatively high degree of literacy among the general population in the ancient Arabic-speaking world. Post-Antiquity illiteracy was made worse by

2646-542: Was made in 1953 when three arrowheads were uncovered, each containing identical Canaanite inscriptions from 12th century BCE. According to Frank Moore Cross , these inscriptions consisted of alphabetic signs that originated during the transitional development from pictographic script to a linear alphabet. Moreover, he asserts, "These inscriptions also provided clues to extend the decipherment of earlier and later alphabetic texts". The Canaanite script's consonantal system inspired alphabetical developments in later systems. During

2700-572: Was not the case in all ancient societies: both Charpin and the EU's emerging scholarship suggest that writing and literacy were far more widespread in Mesopotamia than scholars previously thought. According to social anthropologist Jack Goody , there are two interpretations regarding the origin of the alphabet. Many classical scholars, such as historian Ignace Gelb , credit the Ancient Greeks for creating

2754-519: Was prominent in the Mediterranean region until Neo-Babylonian rulers exiled the Jews to Babylon in the 6th century BCE. It was then that the new script ( Square Hebrew ) emerged, and the older one rapidly died out. The Aramaic alphabet also emerged sometime between 1200 and 1000 BCE. Although early examples are scarce, archeologists have uncovered a wide range of later Aramaic texts, written as early as

2808-574: Was somewhat widespread by the Old Babylonian period. Nonetheless, professional scribes became central to law, finances, accounting, government, administration, medicine, magic, divination, literature, and prayers. Egyptian hieroglyphs emerged between 3300 BCE and 3100 BCE; the iconography emphasized power among royals and other elites. The Egyptian hieroglyphic writing system was the first notation system to have phonetic values; these symbols are called phonograms . Writing in lowland Mesoamerica

2862-669: Was well established in early 18th century England, when books geared towards children became far more common. Near the end of the century, as many as 50 were printed every year in major cities around England. In the 19th century, reading would become even more common in the United Kingdom. Public notes, broadsides, handbills, catchpennies and printed songs would have been usual street literature before newspapers became common. Other forms of popular reading material included advertising for events, theaters, and goods for sale. In his 1836/1837 Pickwick Papers Charles Dickens's said that: even

2916-476: Was written in the chữ Nôm script, consisting of Chinese characters with many characters created locally. Since the 1920s, the script since then used for recording literature has been the Latin-based Vietnamese alphabet .
