Media Control Symbols
In digital electronics, analogue electronics and entertainment, the user interface may include media controls, transport controls or player controls, to enact and change or adjust the process of video playback, Sound, audio playback, and alike. These controls are commonly depicted as widely known symbols found in a multitude of products, exemplifying what is known as dominant design. Symbols Media control symbols are commonly found on both software and physical media players, remote controls, and multimedia keyboards. Their application is described in ISO/IEC 18035. The main symbols date back to the 1960s, with the Pause symbol having reportedly been invented at Ampex during that decade for use on reel-to-reel audio recorder controls, due to the difficulty of translating the word "pause" into some languages used in foreign markets. The Pause symbol was designed as a combination of the existing square Stop symbol and the caesura, and was intended to evoke the concept of an in ...

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 Blocks
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 language, 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 "suppleme ...

Mathematical Operators And Symbols In Unicode
The Unicode Standard encodes almost all standard characters used in mathematics. Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". Dedicated blocks Mathematical Operators block The Mathematical Operators block (U+2200–U+22FF) contains characters for mathematical, logical, and set notation. Supplemental Mathematical Operators block The Supplemental Mathematical Operators block (U+2A00–U+2AFF) contains various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relati ...

Halfwidth And Fullwidth Forms (Unicode Block)
Halfwidth and Fullwidth Forms is a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode. It is the second-to-last block of the Basic Multilingual Plane, followed only by the short Specials block at U+FFF0–FFFF. Its block name in Unicode 1.0 was Halfwidth and Fullwidth Variants. Range U+FF01–FF5E reproduces the characters of ASCII 21 to 7E as fullwidth forms. U+FF00 does not correspond to a fullwidth ASCII 20 (space character), since that role is already fulfilled by U+3000 " ideographic space". Range U+FF61–FF9F encodes halfwidth forms of katakana and related punctuation in a transposition of A1 to DF in the JIS X 0201 encoding – see half-width kana. The range U+FFA0–FFDC encodes halfwidth forms of compatibility jamo characters for Hangul, in a transposition of their 1974 standard layout. It is used in the mapping of some IBM encodings for K ...

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 does not 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.

Tombstone (typography)
In mathematics, the tombstone, halmos, end-of-proof, or Q.E.D. symbol "∎" (or "□") is a symbol used to denote the end of a Mathematical proof, proof, in place of the traditional abbreviation "Q.E.D." for the Latin phrase "''Q.E.D., quod erat demonstrandum''". It is inspired by the Typography, typographic practice of ''wikt:end mark, end marks'', an element that marks the end of an article. In Unicode, it is represented as character . Its graphic form varies, as it may be a hollow or filled rectangle or square. In AMS-LaTeX, the symbol is automatically appended at the end of a proof environment \begin ... \end. It can also be obtained from the commands \qedsymbol, \qedhere or \qed (the latter causes the symbol to be right aligned). It is sometimes called a "Halmos finality symbol" or "halmos" after the mathematician Paul Halmos, who first used it in a mathematical context in 1950. He got the idea of using it from seeing wikt:end mark, end marks in magazines, that is, typograp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 or used in bookbinding to order sections. In the computer industry, a dingbat font or pi font is a computer font that has symbols and shapes located at the code points normally designated for alphabetical or numeric characters. This practice was necessitated by the limited number of code points available in 20th century operating systems. Modern computer fonts containing dingbats are based on Unicode encoding, 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, a ...
