Le terme de systèmes d'écritures africains se réfère à l'usage actuel et historique de systèmes d'écritures sur le continent Africain, comprenant à la fois les indigènes et ceux introduits ultérieurement. Today, the Latin script is commonly encountered across Africa, especially Sub-Saharan Africa. Arabic script is dominant in North Africa and Ge'ez/Ethiopic in the Horn of Africa. Regionally and in some localities, other scripts may be of significant importance.

L'importance de la culture orale et de la tradition en Afrique ainsi que la domination récente des langues européennes par le biais du colonialisme, entre autres, a conduit à l'idée fausse que les langues africaines dans leur ensemble ne posséderaient soit pas de forme écrite, ou n'auraient été mises à l'écrit que très récemment.

Ancien Egyptien et Méroïtique
Il est probable que le système d'écriture du continent africain le plus connu soit les hieroglyphes Egyptiens anciens. These developed later into forms known as Hieratic and Demotic. Still later in ancient history, this system was adapted to the Meroitic script in the upper Nile valley.

Tifinagh
The Tifinagh alphabet is still actively used to varying degrees in trade and modernized forms for writing of Berber languages (Tamazight, Tamashek, etc.) of the Maghreb, Sahara, and Sahel regions (Savage 2008).

Neo-Tifinagh is encoded in the Unicode range U+2D30 to U+2D7F, starting from version 4.1.0. There are 55 defined characters, but there are more characters being used than those defined. In ISO 15924, the code Tfng is assigned to Neo-Tifinagh.

Ge'ez
The Ge'ez script is an abugida that was developed in the Horn of Africa for writing the Ge'ez language. The script is used today in Ethiopia and Eritrea for Amharic, Tigrinya, Tigre, and several other languages. It sometimes called Ethiopic, and is known in Ethiopia as the fidel or abugida (the actual origin of the 21st century linguistic term "abugida", which apply to scripts of India).

Ge'ez or Ethiopic has been computerized and assigned Unicode 3.0 codepoints between U+1200 and U+137F (decimal 4608–4991), containing the basic syllable signs for Ge'ez, Amharic, and Tigrinya, punctuation and numerals.

Nsibidi
Nsibidi (also known as nsibiri, nchibiddi or nchibiddy ) is a system of symbols indigenous to what is now southeastern Nigeria that is apparently an ideographic script, though there have been suggestions that it includes logographic elements. The symbols are at least several centuries old: Early forms appeared on excavated pottery as well as what are most likely ceramic stools and headrests from the Calabar region, with a range of dates from 400 to 1400 CE.

Horn of Africa
Writing systems developed in the twentieth century for transcribing Somali include the Osmanya, Borama and Kaddare alphabets, which were invented by Osman Yusuf Kenadid, Sheikh Abdurahman Sheikh Nuur and Hussein Sheikh Ahmed Kaddare, respectively. The Osmanya script is today available in the Unicode range 10480-104AF [from U+10480 - U+104AF (66688–66735)].

Other writing systems have also been used over the years by different Horn communities. The latter include Sheikh Bakri Sapalo's script for Oromo.

Afrique australe

 * In Southern Africa, the Mwangwego alphabet is used to write Malawian languages.


 * The Mandombe alphabet was invented by Wabeladio Payi in 1978 in the Democratic Republic of the Congo. It is apparently promoted by the Kimbanguist Church and used for writing Kikongo, Lingala, Tshiluba, Swahili, and other languages.

Afrique de l'Ouest
There are various other writing systems native to West Africa and Central Africa. In the last two centuries, a large variety of writing systems have been created in Africa (Dalby 1967, 1968, 1969). Some are still in use today, while others have been largely displaced by non-African writing such as the Arabic alphabet and the Latin alphabet. Below are non-Latin and non-Arabic-based writing systems used to write various languages of Africa.

The Bamum (Bamun; also Shumom) system of pictographic writing was invented beginning in the late 19th-century by Sultan Njoya Ibrahim for writing the Bamun language in what is now Cameroon. It is rarely used today, but a fair amount of material written in this script still exists.

Other modern writing systems developed in West Africa include:


 * Bassa alphabet


 * Bété syllabary


 * The Eghap script was used by the Bagam (Tuchscherer 1999, Rovenchak 2009).


 * Kpelle syllabary
 * Loma syllabary


 * The Mende Ki-ka-ku or KiKaKui syllabary was invented by Kisimi Kamara in Sierra Leone in the early 20th century. It is still used.


 * N'Ko was invented in 1949 by Solomana Kante in Guinea, primarily for the Manding languages. It is apparently in increasing use in West Africa, including some efforts to adapt it to other languages (Wyrod 2008).


 * The Vai syllabary was invented by Mɔmɔlu Duwalu Bukɛlɛ for writing the Vai language in what is now Liberia during the early 19th century. It is still used today.


 * Zaghawa (Beria) was created in 2000 from an earlier proposal made from livestock brands.

Systèmes d'écriture introduits et adaptés
La majorité des alphabets, Grec, Hébreu et Arabe inclus, sont basés sur des alphabets précurseurs. De façon analogue, de nombreux systèmes Africains se sont parallèlement développés de scripts précédents.

Phoenician/Punic
The Phoenicians from what is now Lebanon traded with North Africans and founded cities there, the most famous being Carthage. The Phoenician alphabet is thought to be the origin of many others, including: Arabic, Greek, and Latin. The Carthaginian dialect is called Punic. Today's Tifinagh is thought by some scholars to be descended from Punic, but this is still under debate.

Grec
The Greek alphabet was adapted in Egypt to the Coptic alphabet and language (which is today only a liturgical language). The latter alphabet was in turn adapted to what is now called the Old Nubian alphabet, with the addition of a few letters derived from ancient Meroitic.

Arabe
L' alphabet arabe a été introduit en Afrique par le biais de l'Islam et par le commerce. Apart from its obvious use for the Arabic language, it has been adapted for a number of other languages over the centuries. The Arabic script is still used in some of these cases, but not in others.

It was often necessary to modify the script to accommodate sounds not represented in the script as used for the Arabic language. The adapted form of the script is also called Ajami, especially in the Sahel, and sometimes by specific names for individual languages, such as Wolofal, Sorabe, and Wadaad's writing. Despite the existence of a widely known and well-established script in Ethiopia, there are a few cases where Muslims in Ethiopia have used the Arabic script, instead, for reasons of religious identity.

There are no official standard forms or orthographies, though local usage follows traditional practice for the area or language. There was an effort by ISESCO to standardize Ajami usage. Some critics believe this relied too much on Perso-Arabic script forms and not enough on existing use in Africa. In any event, the effect of that standardization effort has been limited.

Latin
The first systematic attempts to adapt the Latin script to African languages were probably those of Christian missionaries on the eve of European colonization (Pasch 2008). These however were isolated, done by people without linguistic training, and sometimes resulted in competing systems for the same or similar languages.

L'un des défis majeurs dans l'adaptation de l'alphabet Latin à de nombreuses langues africaines était l'usage dans ces dites langues de sons inconnus aux Européens et sans convention d'écriture auxquelles ils pouvaient se référer. Various use was made of letter combinations, modifications, and diacritics do represent such sounds. Some resulting orthographies, such as the Yoruba writing system established by the late 19th century, have remained largely intact.

In many cases, the colonial regimes had little interest in the writing of African languages, but in others they did. In the case of Hausa in Northern Nigeria, for instance, the colonial government was directly involved in determining the written forms for the language.

Since the colonial period, there have been efforts to propose and promulgate standardized or at least harmonized approaches to using the Latin script for African languages. Examples include the Standard Alphabet by Lepsius (mid-19th century) and the Africa Alphabet of the International Institute of African Languages and Cultures (1928, 1930).

Following independence there has been continued attention to the transcription of African languages. In the 1960s and 1970s, UNESCO facilitated several "expert meetings" on the subject, including a seminal meeting in Bamako in 1966, and one in Niamey in 1978. The latter produced the African reference alphabet. Various country-level standardizations have also been made or proposed, such as the Pan-Nigerian Alphabet. A Berber Latin alphabet for northern Berber includes extended Latin characters and two Greek letters.

Such discussions continue, especially on more local scales regarding cross-border languages.

Typewriters
There is not much information on the adaptation of typewriters to African language needs (apart from Arabic, and the African languages that do not use any modified Latin letters). There were apparently some typewriters fitted with keys for typing Nigerian languages. There was at least one IBM Selectric typewriter "typeball" developed for some African languages (including Fula).

Around 1930, the English typewriter was modified by Ayana Birru of Ethiopia to type an incomplete and ligated version of the Amharic alphabet.

The 1982 proposal for a unicase version of the African reference alphabet made by Michael Mann and David Dalby included a suggested typewriter adaptation.

Early computing and fonts
With early desktop computers it was possible to modify existing 8-bit Latin fonts to accommodate specialized character needs. This was done without any kind of system or standardization, meaning incompatibility of encodings.

Similarly, there were diverse efforts (successful, but not standardized) to enable use of Ethiopic/Ge'ez on computers.

Current standards
There was never any ISO 8859 standard for any African languages apart from ISO 8859-6 for (standard) Arabic. One standard - ISO 6438 for bibliographic purposes - was adopted but apparently little used (curiously, although this was adopted at about the same time as the African reference alphabet, there were some differences between the two, indicating perhaps a lack of communication between efforts to harmonize transcription of African languages and the ISO standards process).

Unicode in principle resolves the issue of incompatible encoding, but other questions such as the handling of diacritics in extended Latin scripts are still being raised. These in turn relate to fundamental decisions regarding orthographies of African languages.

In recent years, Osmanya, Tifinagh and N'Ko have been added to Unicode, as have individual characters to other ranges, such as Latin and Arabic. Efforts to encode other African scripts, including minority scripts and major historical writing systems like Egyptian hieroglyphs, are being coordinated by the Script Encoding Initiative.
