Arabic Presentation Forms-B (Unicode Block)
Arabic Presentation Forms-B is a Unicode block encoding spacing forms of Arabic diacritics, and contextual letter forms. The special codepoint ZWNBSP is also here, which is only meant for a byte order mark The byte order mark (BOM) is a particular usage of the special Unicode character, , whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: * The byte order, or endianness, of ... (that may precede text, Arabic or not, or be absent). The block name in Unicode 1.0 was Basic Glyphs for Arabic Language; its characters were re-ordered in the process of merging with ISO 10646 in Unicode 1.0.1 and 1.1. The presentation forms are present only for compatibility with older standards, and are not currently needed for coding text.The Unicode ConsortiumThe Unicode Standard, Version 6.0.0 (Mountain View, CA: The Unicode Consortium, 2011. )Chapter 8/ref> Block History The following Unicode-related documents record t ...

Arabic Script
The Arabic script is the writing system used for Arabic and several other languages of Asia and Africa. It is the second-most widely used List of writing systems by adoption, writing system in the world by number of countries using it or a script directly derived from it, and the third-most by number of users (after the Latin script, Latin and Chinese characters, Chinese scripts). The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam. With the religion's spread, it came to be used as the primary script for many language families, leading to the addition of new letters and other symbols. Such languages still using it are: Persian language, Persian (Western Persian, Farsi/Dari), Malay language, Malay (Jawi alphabet, Jawi), Uyghur language, Uyghur, Kurdish languages, Kurdish, Punjabi language, Punjabi (Shahmukhi), Sindhi language, Sindhi, Balti language, Balti, Balochi language, Balochi, Pashto, Luri language, Lurish, Urdu, Kashmiri lang ...

Script (Unicode)
In Unicode, a script is a collection of letters and other written signs used to represent textual information in one or more writing systems. Some scripts support one and only one writing system and language, for example, Armenian. Other scripts support many different writing systems; for example, the Latin script supports English, French, German, Italian, Vietnamese, Latin itself, and several other languages. Some languages make use of multiple alternate writing systems and thus also use several scripts; for example, in Turkish, the Arabic script was used before the 20th century but transitioned to Latin in the early part of the 20th century. For a list of languages supported by each script, see the list of languages by writing system. More or less complementary to scripts are symbols and Unicode control characters. The unified diacritical characters and unified punctuation characters frequently have the "common" or "inherited" script property. However, the individual s ...

Unicode Block
A Unicode block is one of several contiguous ranges of numeric character codes (code points) of the Unicode character set that are defined by the Unicode Consortium for administrative and documentation purposes. Typically, proposals such as the addition of new glyphs are discussed and evaluated by considering the relevant block or blocks as a whole. Each block is generally, but not always, meant to supply glyphs used by one or more specific languages, or in some general application area such as mathematics, surveying, decorative typesetting, social forums, etc. Design and implementation Unicode blocks are identified by unique names, which use only ASCII characters and are usually descriptive of the nature of the symbols, in English; such as "Tibetan" or "Supplemental Arrows-A". (When comparing block names, one is supposed to equate uppercase with lowercase letters, and ignore any whitespace, hyphens, and underbars; so the last name is equivalent to "supplemental_arrows__a" a ...

ZWNBSP
The word joiner (WJ) is a format character in Unicode used to indicate that word separation should not occur at a position, when using scripts such as Arabic that do not use explicit spacing. It is encoded since Unicode version 3.2 (released in 2002) as . The word joiner does not produce any space and prohibits a line break at its position. Thus, it is a nonbreaking space with zero width. The word joiner replaces the ''zero-width no-break space'' (''ZWNBSP'', U+FEFF), as a usage of the no-break space of zero width. Character U+FEFF is intended for use as a byte order mark (BOM) at the start of a file. However, if encountered elsewhere, it should, according to Unicode, be treated as a zero-width no-break space. The deliberate use of U+FEFF for this purpose is deprecated as of Unicode 3.2, with the word joiner strongly preferred. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Byte Order Mark
The byte order mark (BOM) is a particular usage of the special Unicode character, , whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: * The byte order, or endianness, of the text stream in the cases of 16-bit and 32-bit encodings; * The fact that the text stream's encoding is Unicode, to a high level of confidence; * Which Unicode character encoding is used. BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream. Unicode can be encoded in units of 8-bit, 16-bit, or 32-bit integers. For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. The BOM is encoded in the same scheme as the rest of the document and becomes a Unicode code point if its bytes are swapped. Hence, the process acc ...

Unicode Consortium
The Unicode Consortium (legally Unicode, Inc.) is a 501(c)(3) non-profit organization incorporated and based in Mountain View, California. Its primary purpose is to maintain and publish the Unicode Standard which was developed with the intention of replacing existing character encoding schemes which are limited in size and scope, and are incompatible with multilingual environments. The consortium describes its overall purpose as: Unicode's success at unifying character sets has led to its widespread adoption in the internationalization and localization of software. The standard has been implemented in many technologies, including XML, the Java programming language, Swift, and modern operating systems. Voting members include computer software and hardware companies with an interest in text-processing standards, including Adobe, Apple, the Bangladesh Computer Council, Emojipedia, Facebook, Google, IBM, Microsoft, the Omani Ministry of Endowments and Religious Affairs, ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code identical with the other. ''The Unicode Standard'', however, includes more th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
