Script (Unicode)
In Unicode, a script is a collection of Letter (alphabet), 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 Written language, language, for example, Armenian language, Armenian. Other scripts support many different writing systems; for example, the Latin script in Unicode, Latin script supports English alphabet, English, French alphabet, French, German alphabet, German, Italian alphabet, Italian, Vietnamese language, Vietnamese, Latin alphabet, 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 language, Turkish, the Ottoman Turkish alphabet, 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 co ...

Videotex
Videotex (or interactive videotex) was one of the earliest implementations of an end-user information system. From the late 1970s to early 2010s, it was used to deliver information (usually pages of text) to a user in computer-like format, typically to be displayed on a television or a dumb terminal. In a strict definition, videotex is any system that provides interactive content and displays it on a video monitor such as a television, typically using modems to send data in both directions. A close relative is teletext, which sends data in one direction only, typically encoded in a television signal. All such systems are occasionally referred to as ''viewdata''. Unlike the modern Internet, traditional videotex services were highly centralized. Videotex in its broader definition can be used to refer to any such service, including teletext, the Internet, bulletin board systems, online service providers, and even the arrival/departure displays at an airport. This usage is no longe ... [...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" and ...

Box-drawing Character
Box-drawing characters, also known as line-drawing characters, are a form of semigraphics widely used in text user interfaces to draw various geometric frames and boxes. Box-drawing characters typically only work well with monospaced fonts. In graphical user interfaces, these characters are much less useful as it is more simple and appropriate to draw lines and rectangles directly with graphical APIs. However, they are still useful for command-line interfaces and plaintext comments within source code. Used along with box-drawing characters are block elements, shade characters, and terminal graphic characters, these can be used for filling regions of the screen and portraying drop shadows. Encodings Unicode Box Drawing Unicode includes 128 such characters in the Box Drawing block. In many Unicode fonts only the subset that is also available in the IBM PC character set (see below) will exist, due to it being defined as part of the WGL4 character set.

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, Monotype ...

Dingbat
In typography, a dingbat (sometimes more formally known as a printer's ornament or printer's character) is an ornament, specifically, a glyph used in typesetting, often employed to create box frames, (similar to box-drawing characters) or as a dinkus (section divider). Some of the dingbat symbols have been used as signature marks, used in bookbinding to order sections. In the computer industry, a Dingbat font was a computer font that has symbols and shapes that reused the code points designated for alphabetical or numeric characters. This practice was necessitated by the limited number of code points available in 20th century operating systems. Most modern fonts are based on Unicode, which has unique code points for dingbat glyphs. Examples Examples of characters included in Unicode (ITC Zapf Dingbats series 100 and others): Dingbats Unicode block Unicode provides code points for many commonly used dingbats, as listed below. Prior to widespread adoption of Unicode i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Block Elements
Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. These can be used for filling regions of the screen and portraying drop shadows. Its block name in Unicode 1.0 was Blocks. Character table Font coverage Font sets like Code2000 and the DejaVu family—include coverage for each of the glyphs in the Block Elements range, Unifont also contains all the glyphs. Among the fonts in widespread use, full implementation is provided by Segoe UI Symbol. The glyphs in Block Elements each share the same character width in most supported fonts, allowing them to be used graphically in row and column arrangements. However, the block doesn't contain a space character of its own and ASCII space may or may not render at the same width as Block Elements glyphs, as those characters are intended to be used exclusively for monospaced fonts.

Geometric Shapes
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF. U+25A0–U+25CF The BLACK CIRCLE is displayed when typing in a password field, in order to hide characters from a screen recorder or shoulder surfing. U+25D0–U+25FF The CIRCLE WITH LEFT HALF BLACK is used to represent the contrast ratio of a screen. Font coverage Font sets like Code2000 and the DejaVu family include coverage for each of the glyphs in the Geometric Shapes range. Unifont also contains all the glyphs. Among the fonts in widespread use, full implementation is provided by Segoe UI Symbol and significant partial implementation of this range is provided by Arial Unicode MS and Lucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively. Block Emoji The Geometric Shapes block contains eight emoji: U+25AA–U+25AB, U+25B6, U+25C0 and U+25FB–U+25FE. The block has sixteen standardized variants defined to specify ...

Code Page 437
Code page 437 (CCSID 437) is the character set of the original IBM PC (personal computer). It is also known as CP437, OEM-US, OEM 437, PC-8, or DOS Latin US. The set includes all printable ASCII characters as well as some accented letters (diacritics), Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "extended ASCII" (one of many mutually incompatible ASCII extensions). This character set remains the primary set in the core of any EGA and VGA-compatible graphics card. As such, text shown when a PC reboots, before fonts can be loaded and rendered, is typically rendered using this character set. Many file formats developed at the time of the IBM PC are based on code page 437 as well. Display adapters The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8×8 pixels-per-character font of the Color Graphics Adapter ( CGA) ca ...

Semigraphics
Text-based semigraphics or pseudographics is a primitive method used in early text mode video hardware to emulate raster graphics without having to implement the logic for such a display mode. There are two different ways to accomplish the emulation of raster graphics. The first one is to create a low-resolution all points addressable mode using a set of special characters with all binary combinations of a certain subdivision matrix of the text mode character size; this method is referred to as block graphics, or sometimes mosaic graphics. The second one is to use special shapes instead of glyphs (letters and figures) that appear as if drawn in raster graphics mode, sometimes referred to as semi- or pseudo-graphics; an important example of this is box-drawing characters. Semigraphical characters (including some block elements) are still incorporated into the BIOS of any VGA compatible video card, so any PC can display these characters from the moment it is turned on, even whe ...
