Typography
Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing ( leading), and letter-spacing (tracking), as well as adjusting the space between pairs of letters (kerning). The term ''typography'' is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process. Type design is a closely related craft, sometimes considered part of typography; most typographers do not design typefaces, and some type designers do not consider themselves typographers. Typography also may be used as an ornamental and decorative device, unrelated to the communication of information. Typography is the work of typesetters (also known as compositors), typographers, graphic designers, art directors, manga artists, comic book artists, and, now, anyone who arranges words, letters, numbers ...

Digraph (orthography)
A digraph or digram (from the grc, δίς , "double" and , "to write") is a pair of characters used in the orthography of a language to write either a single phoneme (distinct sound), or a sequence of phonemes that does not correspond to the normal values of the two characters combined. Some digraphs represent phonemes that cannot be represented with a single character in the writing system of a language, like the English '' sh'' in ''ship'' and ''fish''. Other digraphs represent phonemes that can also be represented by single characters. A digraph that shares its pronunciation with a single character may be a relic from an earlier period of the language when the digraph had a different pronunciation, or may represent a distinction that is made only in certain dialects, like the English '' wh''. Some such digraphs are used for purely etymological reasons, like '' rh'' in English. Digraphs are used in some Romanization schemes, like the '' zh'' often used to represent the Ru ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), 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 script (Unicode), 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 id ...

Orthographic Ligature
In writing and typography, a ligature occurs where two or more graphemes or letters are joined to form a single glyph. Examples are the characters æ and œ used in English and French, in which the letters 'a' and 'e' are joined for the first ligature and the letters 'o' and 'e' are joined for the second ligature. For stylistic and legibility reasons, 'f' and 'i' are often merged to create 'fi' (where the tittle on the 'i' merges with the hood of the 'f'); the same is true of 's' and 't' to create 'st'. The common ampersand (&) developed from a ligature in which the handwritten Latin letters 'E' and 't' (spelling , Latin for 'and') were combined. History The earliest known script Sumerian cuneiform and Egyptian hieratic both include many cases of character combinations that gradually evolve from ligatures into separately recognizable characters. Other notable ligatures, such as the Brahmic abugidas and the Germanic bind rune, figure prominently throughout ancient manus ...

Digraph (computing)
In computer programming, digraphs and trigraphs are sequences of two and three characters, respectively, that appear in source code and, according to a programming language's specification, should be treated as if they were single characters. Various reasons exist for using digraphs and trigraphs: keyboards may not have keys to cover the entire character set of the language, input of special characters may be difficult, text editors may reserve some characters for special use and so on. Trigraphs might also be used for some EBCDIC code pages that lack characters such as . History The basic character set of the C programming language is a subset of the ASCII character set that includes nine characters which lie outside the ISO 646 invariant character set. This can pose a problem for writing source code when the encoding (and possibly keyboard) being used does not support any of these nine characters. The ANSI C committee invented trigraphs as a way of entering source code using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Directed Graph
In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph that is made up of a set of vertices connected by directed edges, often called arcs. Definition In formal terms, a directed graph is an ordered pair where * ''V'' is a set whose elements are called '' vertices'', ''nodes'', or ''points''; * ''A'' is a set of ordered pairs of vertices, called ''arcs'', ''directed edges'' (sometimes simply ''edges'' with the corresponding set named ''E'' instead of ''A''), ''arrows'', or ''directed lines''. It differs from an ordinary or undirected graph, in that the latter is defined in terms of unordered pairs of vertices, which are usually called ''edges'', ''links'' or ''lines''. The aforementioned definition does not allow a directed graph to have multiple arrows with the same source and target nodes, but some authors consider a broader definition that allows directed graphs to have such multiple arcs (namely, they allow the arc set to be a m ...

CIA Cryptonym
CIA cryptonyms are code names or code words used by the U.S. Central Intelligence Agency (CIA) to refer to projects, operations, persons, agencies, etc. Format of cryptonyms CIA cryptonyms sometimes contain a two character prefix called a digraph, which designates a geographical or functional area. Certain digraphs were changed over time; for example, the digraph for the Soviet Union changed at least twice. The rest is either an arbitrary dictionary word, or occasionally the digraph and the cryptonym combine to form a dictionary word (e.g., AEROPLANE) or can be read out as a simple phrase (e.g., WIBOTHER, read as "Why bother!"). Cryptonyms are sometimes written with a slash after the digraph, e.g., ZR/RIFLE, and sometimes in one sequence, e.g., ZRRIFLE. The latter format is the more common style in CIA documents. Examples from publications by former CIA personnel show that the terms "code name" and "cryptonym" can refer to the names of operations as well as to individual persons ...

List Of ISO 639-1 Codes
ISO 639 is a standardized nomenclature used to classify languages. Each language is assigned a two-letter (639-1) and three-letter ( and ) lowercase abbreviation, amended in later versions of the nomenclature. This table lists all of: * ISO 639-1: two-letter codes, one per language for ISO 639 macrolanguage And some of: * ISO 639-2/T: three-letter codes, for the same languages as 639-1 * ISO 639-2/B: three-letter codes, mostly the same as , but with some codes derived from English names rather than native names of languages (in the following table, these differing codes are highlighted in boldface) * ISO 639-3 ISO 639-3:2007, ''Codes for the representation of names of languages – Part 3: Alpha-3 code for comprehensive coverage of languages'', is an international standard for language codes in the ISO 639 series. It defines three-letter codes for ...: three-letter codes, the same as for languages, but with distinct codes for each variety of an ISO 639 macrolanguage T ...

Protractor
A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Some protractors are simple half-discs or full circles. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle. Typical Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts. Some precision protractors further divide degrees into arcminutes. They are used in mechanics, engineering and geometry. Bevel A bevel protractor is a graduated circular protractor with one pivoted arm; used for measuring or marking off angles. Sometimes Vernier scales are attached to give more precise readings. It has wide application in architectural and mechanical drawing, although its use is decreasing with the availability of modern drawing software or CAD. Universal bevel protractors are also used by toolmakers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digraphia
In sociolinguistics, digraphia refers to the use of more than one writing system for the same language. Synchronic digraphia is the coexistence of two or more writing systems for the same language, while diachronic digraphia (or sequential digraphia) is the replacement of one writing system by another for a particular language. Hindustani language, Hindustani, with an Urdu literary standard written in Urdu alphabet and a High Hindi standard written in Devanagari, is one of the 'textbook examples' of synchronic digraphia, cases where writing systems are used contemporaneously. An example of diachronic digraphia, where one writing system replaces another, occurs in the case of Turkish, for which the traditional Arabic script, Arabic writing system was replaced with a Latin-based system in 1928. Digraphia has implications in language planning, language policy, and language ideology. Terminology Etymology English wikt:digraphia, ''digraphia'', like French language, French wikt:digr ...
