ISO 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 rather of 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 (''accents''). 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ITU-T
The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU). It is responsible for coordinating standards for telecommunications and Information Communication Technology such as X.509 for cybersecurity, Y.3172 and Y.3173 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. The first meeting of the World Telecommunication Standardization Assembly (WTSA), the sector's governing conference, took place on 1 March of that year. ITU-T has a permanent secretariat called the Telecommunication Standardization Bureau (TSB), which is based at the ITU headquarters in Geneva, Switzerland. The current director of the TSB is Chaesub Lee (of South Korea), whose first 4-year term commenced on 1 January 2015, and whose second 4-year term commenced on 1 January 2019. Chaesub Lee succeeded Malcolm Johnson (Director), Malc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanian Language
Romanian (obsolete spellings: Rumanian or Roumanian; autonym: ''limba română'' , or ''românește'', ) is the official and main language of Romania and the Moldova, Republic of Moldova. As a minority language it is spoken by stable communities in the countries surrounding Romania (Romanians in Bulgaria, Bulgaria, Romanians in Hungary, Hungary, Romanians of Serbia, Serbia, and Romanians in Ukraine, Ukraine), and by the large Romanian diaspora. In total, it is spoken by 28–29 million people as an First language, L1+Second language, L2, of whom 23–24 millions are native speakers. In Europe, Romanian is rated as a medium level language, occupying the tenth position among thirty-seven Official language, official languages. Romanian is part of the Eastern Romance languages, Eastern Romance sub-branch of Romance languages, a linguistic group that evolved from several dialects of Vulgar Latin which separated from the Italo-Western languages, Western Romance languages in the co ...

Combining Character
In digital typography, combining characters are characters that are intended to modify other characters. The most common combining characters in the Latin script are the combining diacritical marks (including combining accents). Unicode also contains many precomposed characters, so that in many cases it is possible to use both combining diacritics and precomposed characters, at the user's or application's choice. This leads to a requirement to perform Unicode normalization before comparing two Unicode strings and to carefully design encoding converters to correctly map all of the valid ways to represent a character in Unicode to a legacy encoding to avoid data loss. In Unicode, the main block of combining diacritics for European languages and the International Phonetic Alphabet is U+0300–U+036F. Combining diacritical marks are also present in many other blocks of Unicode characters. In Unicode, diacritics are always added after the main character (in contrast to some older c ...

Latin-2
ISO/IEC 8859-2:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 2: Latin alphabet No. 2'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as "Latin-2". It is generally intended for Central or "Eastern European" languages that are written in the Latin script. Note that ISO/IEC 8859-2 is very different from code page 852 (MS-DOS Latin 2, PC Latin 2) which is also referred to as "Latin-2" in Czech and Slovak regions. Code page 912 is an extension. Almost half the use of the encoding is for Polish, and it's the main legacy encoding for Polish, while virtually all use of it has been replaced by UTF-8 (on the web). ISO-8859-2 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. Less than 0.04% of all web pages use ISO-8859-2 as of October 2022. Microsoft has assigned code page 28592 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin-5
ISO/IEC 8859-9:1999, ''Information technology — 8-bit single-byte coded graphic character sets — Part 9: Latin alphabet No. 5'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1989. It is designated ECMA-128 by Ecma International and TS 5881 as a Turkish standard. It is informally referred to as Latin-5 or ''Turkish''. It was designed to cover the Turkish language (which is its dominant user, even though it can be used for some other languages too), designed as being of more use than the ISO/IEC 8859-3 encoding. It is identical to ISO/IEC 8859-1 except for the replacement of six Icelandic characters ( Ðð, Ýý, Þþ) with characters unique to the Turkish alphabet ( Ğğ, İ, ı, Şş). ISO-8859-9 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. In modern applications Unicode and UTF-8 are preferred; authors of new web pages and the desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin-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. ISO-8859-1 was (according to the standard, at least) the default encoding of documents delivered via HTTP with a MIME type beginning with "text/" (HTML5 changed this to Windows-1252). , 1.3% of all (but only 8 of the top 1000) web sites use . It is the most ''declared'' single-byte character encoding in the world on the Web, but as Web browsers interpret it as the superset Windows-1252, the documents m ...

ISO/IEC 10646
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 tec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escape Sequence
In computer science, an escape sequence is a combination of characters that has a meaning other than the literal characters contained therein; it is marked by one or more preceding (and possibly terminating) characters. Examples * In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. ** Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth translation phase. ** To represent the backslash character itself, \\ can be used, whereby the first backslash indicates an escape and the second specifies that a backslash is being escaped. ** A character may be escaped in multiple different ways. Assuming ASCII encoding, the escape sequences \x5c (hexadecimal), \\, \134 (octal) and \x5C all encode the same character: ...

ISO-IR
ISO/IEC 2022 ''Information technology—Character code structure and extension techniques'', is an ISO/IEC standard (equivalent to the ECMA standard ECMA-35, the ANSI standard ANSI X3.41 and the Japanese Industrial Standard JIS X 0202) in the field of character encoding. Originating in 1971, it was most recently revised in 1994. ISO 2022 specifies a general structure which character encodings can conform to, dedicating particular ranges of bytes ( 0x00–1F and 0x7F–9F) to be used for non-printing control codes for formatting and in-band instructions (such as line breaks or formatting instructions for text terminals), rather than graphical characters. It also specifies a syntax for escape sequences, multiple-byte sequences beginning with the control code, which can likewise be used for in-band instructions. Specific sets of control codes and escape sequences designed to be used with ISO 2022 include ISO/IEC 6429, portions of which are implemented by ANSI.SYS and terminal emu ...

Hexadecimal
In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, a number of ...

International Currency Sign
The currency sign is a character used to denote an unspecified currency. It can be described as a circle the size of a lowercase character with four short radiating arms at 45° (NE), 135° (SE), 225° (SW) and 315° (NW). It is raised slightly above the baseline. The character is sometimes called scarab. History The symbol was first encoded for computers in 1972, as a placeholder for national currency symbols such as the dollar sign, in national variants (ISO 646) of ASCII and the International Reference Variant. It was proposed by Italy as an alternative (to the dollar sign) at 0x24. In reality, most national standards retained the dollar sign as too important. ASCII and ISO 646 were specified as 7-bit encoding, which allowed for 96 printable characters and 32 control codes. The character is used in the GSM default 7-bit encoding as specified in 3GPP TS 23.038 / GSM 03.38 at 0x24. The introduction of 8-bit encoding and the ISO/IEC 8859 code pages meant that all major na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
