Braille Patterns
The Unicode block Braille Patterns (U+2800..U+28FF) contains all 256 possible patterns of an 8-dot braille cell, thereby including the complete 6-dot cell range.Unicode Chapter 15 section 15.10 In Unicode, a braille cell does not have a letter or meaning defined. For example, Unicode does ''not'' define to be "R". Independent script In themselves, braille letters do not belong to any print script, but constitute a distinct braille script. The same braille letter can be used to transcribe multiple scripts, e.g. Latin, Cyrillic, Greek and even elements of Chinese characters, as well as digits. Thus while transcribes the letter ''h'' of the Latin script, as well as the digit ''8'', it transcribes ᄐ ''t-'' of Korean |
Braille
Braille ( , ) is a Tactile alphabet, tactile writing system used by blindness, blind or visually impaired people. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. For blind readers, braille is an independent writing system, rather than a code of printed orthography. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first Binary numeral system, binary form of writing developed in the modern era. Braille characters are f ...

Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

ISO/IEC JTC 1/SC 2
ISO/IEC JTC 1/SC 2 Coded character sets is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), that develops and facilitates standards within the field of coded character sets. The international secretariat of ISO/IEC JTC 1/SC 2 is the Japanese Industrial Standards Committee (JISC), located in Japan. SC 2 is responsible for the development of the Universal Coded Character Set standard (ISO/IEC 10646), which is the international standard corresponding to the Unicode Standard. History The subcommittee was established in 1987 under ISO/TC 97 as ISO/TC 97/SC 2, originally with the title "Character Sets and Information Coding", with the area of work being, "the standardization of bit and byte coded representation of information for interchange including among others, sets of graphic characters, of control functions, of picture elements and audi ...

Unicode Consortium
The Unicode Consortium (legally Unicode, Inc.) is a 501(c)(3) non-profit organization incorporated and based in Mountain View, California, U.S. Its primary purpose is to maintain and publish the Unicode Standard which was developed with the intention of replacing existing character encoding schemes that are limited in size and scope, and are incompatible with multilingual environments. 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. Members are usually but not limited to 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, Monotype Imaging, Netflix, Sales ...

Text-mode User Interface
In computing, text-based user interfaces (TUI) (alternately terminal user interfaces, to reflect a dependence upon the properties of computer terminals and not just text), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire screen area and may accept mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator. Types of text terminals From text application's point of view, a text screen (and communications with it) can belong to one of three types (here ordered in order of decreasing accessibility): # A genuine text mode display, controlled by a video adapter or the central processor itself. This is a normal condition for a locally running application ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DejaVu Fonts
The DejaVu fonts are a font superfamily, superfamily of computer font, fonts designed for Open-source Unicode typefaces, broad coverage of the Unicode Universal Character Set. The fonts are derived from Bitstream Vera (sans-serif) and Bitstream Charter (serif), two fonts released by Bitstream Inc., Bitstream under a free license that allowed derivative works based upon them; the Vera and Charter families were limited mainly to the characters in the Basic Latin (Unicode block), Basic Latin and Latin-1 Supplement portions of Unicode, roughly equivalent to ISO/IEC 8859-15, and Bitstream's licensing terms allowed the fonts to be expanded upon without explicit authorization. The DejaVu fonts project was started with the aim to "provide a wider range of characters ... while maintaining the original look and feel through the process of collaborative development". The development of the fonts is done by many contributors and is organized through a wiki and a mailing list. The DejaVu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Braille ASCII
Braille ASCII (or more formally The North American Braille ASCII Code, also known as SimBraille) is a subset of the ASCII character set which uses 64 of the printable ASCII characters to represent all possible dot combinations in six-dot braille. It was developed around 1969 and, despite originally being known as North American Braille ASCII, it is now used internationally. Overview Braille ASCII uses the 64 ASCII characters between 32 and 95 inclusive. All capital letters in ASCII correspond to their equivalent values in uncontracted English Braille. Note however that, unlike standard print, there is only one braille symbol for each letter of the alphabet. Therefore, in Braille, all letters are lower-case by default, unless preceded by a capitalization sign ( ). The numbers 1 through 9 and 0 correspond to the letters ''a'' through ''j'', except that they are lowered or shifted lower in the Braille cell. For example, represents ''c'', and is ''3''. The other symbols m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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", ...

Endianness is primarily expressed as big-endian (BE) or little-endian (LE), terms introduced by Danny Cohen (computer scientist), Danny Cohen into computer science for data ordering in an Internet Experiment Note published in 1980. Also published at The adjective ''endian'' has its origin in the writings of 18th century Anglo-Irish writer Jonathan Swift. In the 1726 novel ''Gulliver's Travels'', he portrays the conflict between sects of Lilliputians divided into those breaking the shell of a boiled egg from the big end or from the little end.
