Pango (Company)
Pango (stylized as Παν語) is a text (i.e. glyph) layout engine library which works with the HarfBuzz shaping engine for displaying multi-language text. Full-function rendering of text and cross-platform support is achieved when Pango is used with platform APIs or third-party libraries, such as Uniscribe and FreeType, as text rendering backends. Pango-processed text will appear similar under different operating systems. Pango is a special-purpose library for text and not a general-purpose graphics rendering library such as Cairo, with which Pango can be used. The Cairo documentation recommends Pango be used to "render" text rather than Cairo for all but the simplest text "rendering". History and naming The name pango comes from Greek ''pan'' ( παν, ) and Japanese ''go'' ( 語, ). In January 2000, the merger of the GScript and GnomeText projects was named Pango. Pango version 1.0.0 was released 11 March 2002. Support for OpenType features Pango 1.17 and newer sup ...

Romanian Alphabet
The Romanian alphabet is a variant of the Latin alphabet used for writing the Romanian language. It consists of 31 letters, five of which (Ă, Â, Î, Ș, and Ț) have been modified from their Latin originals for the phonetic requirements of the language. The letters Q (''chiu''), W (''dublu ve''), and Y (''igrec'' or ''i grec,'' meaning "Greek i") were formally introduced in the Romanian alphabet in 1982, although they had been used earlier. They occur only in foreign words and their Romanian derivatives, such as ''quasar'', ''watt'', and ''yoga''. The letter ''K'', although relatively older, is also rarely used and appears only in proper names and international neologisms such as ''kilogram'', ''broker'', ''karate''. These four letters are still perceived as foreign, which explains their usage for stylistic purposes in words such as ''nomenklatură'' (normally ''nomenclatură'', meaning "nomenclature", but sometimes spelled with ''k'' instead of ''c'' if referring to member ...

C (programming Language) Libraries
C, or c, is the third letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical E ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Computer Font
A computer font is implemented as a digital data file containing a set of graphically related glyphs. A computer font is designed and created using a font editor. A computer font specifically designed for the computer screen, and not for printing, is a screen font. In the terminology of movable type, movable metal type, a ''typeface'' is a set of characters that share common design features across styles and sizes (for example, all the varieties of Gill Sans), while a ''font'' is a set of pieces of movable type in a specific typeface, size, width, weight, slope, etc. (for example, Gill Sans bold 12 point). In HTML, CSS, and related technologies, the Font family (HTML), font family attribute refers to the digital equivalent of a typeface. Since the 1990s, many people outside the printing industry have used the word ''font'' as a synonym for ''typeface''. There are three basic kinds of computer font file data formats: * Bitmap fonts consist of a matrix of dots or pixels represent ...

Typographic 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 and used in English and French, in which the letters and are joined for the first ligature and the letters and are joined for the second ligature. For stylistic and legibility reasons, and are often merged to create (where the tittle on the merges with the hood of the ); the same is true of and to create . The common ampersand, , developed from a ligature in which the handwritten Latin letters and (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 manuscripts. These new glyphs emerge alongside the p ...

WorldScript
WorldScript is the multilingual text rendering engine for Apple Macintosh's classic Mac OS, before Mac OS X was introduced. Starting with version 7.1, Apple unified the implementation of non-Roman script systems in a programming interface called WorldScript. WorldScript I was used for all one-byte character sets and WorldScript II for two-byte sets. Support for new script systems was added by so-called Language Kits. Some kits were provided with foreign versions of the system software, and others were sold by Apple and third parties. Application support for WorldScript was not universal, since building in support was a significant task. In 8.5, full Unicode support was added to Mac OS through an API called Apple Type Services for Unicode Imaging (ATSUI). However, WorldScript remained the dominant technology for international text until Mac OS X, because of limited application support for ATSUI. Legacy Good international support gave a marketing edge to word-processing programs s ...

Graphite (smart Font Technology)
Graphite is a programmable Unicode-compliant smart font technology and rendering system developed by SIL International as free software, distributed under the terms of the GNU Lesser General Public License and the Common Public License. Capabilities and comparison to other smart font technologies Graphite is based on the TrueType font format, and adds three of its own tables. It allows for a variety of rendering rules, including Typographic ligature, ligatures, glyph substitution, glyph insertion, glyph rearrangement, anchoring diacritics, kerning, and Justification (typesetting), justification. Graphite rules may be sensitive to the context. For instance, there might be a glyph substitution rule that replaces every non-final ''s'' by an ''Long s, ſ''. In a Graphite font, all smart rendering information resides within the font file. In order to display the Graphite smart rendering, an application needs only Graphite support, but no built-in knowledge about the writing system’ ...
