Iso Basic Latin Alphabet
The ISO basic Latin alphabet is an international standard (beginning with ISO/IEC 646) for a Latin-script alphabet that consists of two sets (uppercase and lowercase) of 26 letters, codified in various national and international standards and used widely in international communication. They are the same letters that comprise the current English alphabet. Since medieval times, they are also the same letters of the modern Latin alphabet. The order is also important for sorting words into alphabetical order. The two sets contain the following 26 letters each: History By the 1960s it became apparent to the computer and telecommunications industries in the First World that a non-proprietary method of encoding characters was needed. The International Organization for Standardization (ISO) encapsulated the Latin script in their ( ISO/IEC 646) 7-bit character-encoding standard. To achieve widespread acceptance, this encapsulation was based on popular usage. The standard was ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin-script Alphabet
A Latin-script alphabet (Latin alphabet or Roman alphabet) is an alphabet that uses Letter (alphabet), letters of the Latin script. The 21-letter archaic Latin alphabet and the 23-letter classical Latin alphabet belong to the oldest of this group. The 26-letter modern Latin alphabet is the newest of this group. Encoding The 26-letter ISO basic Latin alphabet (adopted from the earlier ASCII) contains the 26 letters of the English alphabet. To handle the many other alphabets also derived from the classical Latin one, ISO and other telecommunications groups "extended" the ISO basic Latin multiple times in the late 20th century. More recent international standards (e.g. Unicode) include those that achieved ISO adoption. Key types of differences Apart from alphabets for modern spoken languages, there exist phonetic alphabets and spelling alphabets in use derived from Latin script letters. Historical languages may also have used (or are now studied using) alphabets that are deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin Characters In Unicode
Over a thousand characters from the Latin script are encoded in the Unicode Standard, grouped in several basic and extended Latin blocks. The extended ranges contain mainly precomposed letters plus diacritics that are equivalently encoded with combining diacritics, as well as some ligatures and distinct letters, used for example in the orthographies of various African languages (including click symbols in Latin Extended-B) and the Vietnamese alphabet (Latin Extended Additional). Latin Extended-C contains additions for Uighur and the Claudian letters. Latin Extended-D comprises characters that are mostly of interest to medievalists. Latin Extended-E mostly comprises characters used for German dialectology (Teuthonista). Latin Extended-F and -G contain characters for phonetic transcription. Blocks As of version of the Unicode Standard, 1,487 characters in the following 19 blocks are classified as belonging to the Latin script. * Basic Latin, 0000–007F. This block correspon ...

ISO/IEC 8859-1
ISO/IEC 8859-1:1998, ''Information technology—8-bit single-byte coded graphic character sets—Part 1: Latin alphabet No. 1'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. ISO/IEC 8859-1 encodes what it refers to as "Latin alphabet no. 1", consisting of 191 characters from the Latin script. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is the basis for some popular 8-bit character sets and the first two blocks of characters in Unicode. , 1.1% of all web sites use . It is the most declared single-byte character encoding, but as Web browsers and the HTML5 standard interpret them as the superset Windows-1252, these documents may include characters from that set. Some countries or languages show a higher usage than the global average, in 2025 Brazil according to website use, use is at 2.9%, and in Germany at 2.3%. ISO-8859-1 was (ac ...

ISO/IEC 6937
T.51 / ISO/IEC 6937:2001, ''Information technology — Coded graphic character set for text communication — Latin alphabet'', is a multibyte extension of ASCII, or more precisely ISO/IEC 646-IRV. It was developed in common with ITU-T (then CCITT) for telematic services under the name of ''T.51'', and first became an ISO standard in 1983. Certain byte codes are used as lead bytes for letters with diacritics. The value of the lead byte often indicates which diacritic that the letter has, and the follow byte then has the ASCII-value for the letter that the diacritic is on. ISO/IEC 6937's architects were Hugh McGregor Ross, Peter Fenwick, Bernard Marti and Loek Zeckendorf. ISO6937/2 defines 327 characters found in modern European languages using the Latin alphabet. Non-Latin European characters, such as Cyrillic and Greek, are not included in the standard. Also, some diacritics used with the Latin alphabet like the Romanian comma are not included, using cedilla instead as no di ...

ISO/IEC
ISO/IEC JTC 1, entitled "Information technology", is a joint technical committee (JTC) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Its purpose is to develop, maintain and promote standards in the fields of information and communications technology (ICT). JTC 1 has been responsible for many critical IT standards, ranging from the Joint Photographic Experts Group (JPEG) image formats and Moving Picture Experts Group (MPEG) audio and video formats to the C and C++ programming languages. History ISO/IEC JTC 1 was formed in 1987 as a merger between ISO/TC 97 (Information Technology) and IEC/TC 83, with IEC/SC 47B joining later. The intent was to bring together, in a single committee, the IT standardization activities of the two parent organizations in order to avoid duplicative or possibly incompatible standards. At the time of its formation, the mandate of JTC 1 was to develop base standards in information t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 646
ISO/IEC 646 ''Information technology — ISO 7-bit coded character set for information interchange'', is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard in the field of character encoding. It is equivalent to the Ecma International, ECMA standard ECMA-6 and developed in cooperation with ASCII at least since 1964. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. The first edition of ISO/IEC 646 was published in 1973, and the most recent, third, edition in 1991. ISO/IEC 646 specifies a 7-bit character code from which several national standards are derived. It allocates a set of 82 unique graphic characters to 7-bit code points, known as the ''invariant'' (INV) or ''basic character set'', including letters of the ISO basic Latin alphabet, Numerical digit, digits, and some common English language, English pun ...

EBCDIC
Extended Binary Coded Decimal Interchange Code (EBCDIC; ) is an eight- bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. It descended from the code used with punched cards and the corresponding six-bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is supported by various non-IBM platforms, such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, the SDS Sigma series, Unisys VS/9, Unisys MCP and ICL VME. History EBCDIC was devised in 1963 and 1964 by IBM and was announced with the release of the IBM System/360 line of mainframe computers. It is an eight-bit character encoding, developed separately from the seven-bit ASCII encoding scheme. It was created to extend the existing Binary-Coded Decimal (BCD) Interchange Code, or BCDIC, which itself was devised as an efficient means of encoding the two ''zone'' and ''number'' punches on punched cards into six ...

Radiotelephony Spelling Alphabet
The International Radiotelephony Spelling Alphabet or simply the Radiotelephony Spelling Alphabet, commonly known as the NATO phonetic alphabet, is the most widely used set of clear-code words for communicating the letters of the Latin/Roman alphabet. Technically a ''radiotelephonic spelling alphabet'', it goes by various names, including NATO spelling alphabet, ICAO phonetic alphabet, and ICAO spelling alphabet. The ITU phonetic alphabet and figure code is a rarely used variant that differs in the code words for digits. Although spelling alphabets are commonly called "phonetic alphabets", they are not phonetic in the sense of phonetic transcription systems such as the International Phonetic Alphabet. To create the code, a series of international agencies assigned 26 clear-code words (also known as "phonetic words") acrophonically to the letters of the Latin alphabet, with the goal that the letters and numbers would be easily distinguishable from one another over radio ...
