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.

GNU Unifont
GNU Unifont is a free Unicode bitmap font created by Roman Czyborra. The main Unifont covers all of the Basic Multilingual Plane (BMP). The "upper" companion covers significant parts of the Supplementary Multilingual Plane (SMP). The "Unifont JP" companion contains Japanese kanji present in the JIS X 0213 character set. It is present in most free operating systems and windowing systems such as Linux, XFree86 or the X.Org Server, some embedded firmware such as RockBox, as well as in Minecraft Java Edition. The source code is released under the GNU General Public License, GPL-2.0-or-later license. The font is released under the GNU General Public License, GPL-2.0-or-later license with GPL font exception, Font-exception-2.0 (embedding the font in a document does not require the document to be placed under the same license); and from version 13.0.04, dual-licensed under SIL Open Font License, SIL Open Font License 1.1.

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. These characters are characterized by being designed to be connected horizontally and/or vertically with adjacent characters, which requires proper alignment. Box-drawing characters therefore typically only work well with monospaced fonts. In graphical user interfaces, these characters are much less useful as it is simpler to draw lines and rectangles directly with graphical APIs. However, they are still useful for command-line interfaces and plaintext Comment (computer programming), comments within source code. Some recent embedded systems also use proprietary character sets, usually extensions to ISO 8859 character sets, which include box-drawing characters or other special symbols. Other types of box-drawing characters are block elements, shade characters, and terminal graphic characters; these can be used ...

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 MS-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 9ร14 pixels-per-character font stored in the ROM of the IBM Monochrome Display Adapter (MDA) and an 8ร8 pixels-per-character font of the Color Graphics Adapter ( ...

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 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. More or less complementary to scripts are Unicode symbols, symbols and Unicode control characters. The unified Combi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Operators
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation. Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (ยฑ), multiplication sign (ร) and obelus (รท), due to them already appearing in the Latin-1 Supplement block, although a distinct minus sign (−) is included, semantically different from the Basic Latin hyphen-minus (-). Block Variation sequences The Mathematical Operators block has sixteen variation sequences defined for standardized variants. They use (VS01) to denote variant symbols (depending on the font): History The following Unicode-related documents record the purpose and process of defining specific characters in the Mathematical Operators block: See also * Mathematical operators and symbols in Unicode * Supplemental Mathematical Operators Supplemental Mathema ...

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 โ 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 ...

Tombstone (typography)
In mathematics, the tombstone, halmos, end-of-proof, or Q.E.D. symbol "โ" (or "โก") 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] |
Semigraphics
Text-based semigraphics, pseudographics, or character graphics 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 ...

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 ...

Geometric Shapes (Unicode Block)
Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0โ25FF. Font coverage Font sets like Code2000 and the DejaVu fonts, DejaVu family include coverage for each of the glyphs in the Geometric Shapes range. GNU Unifont, 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+25AAโU+25AB, U+25B6, U+25C0 and U+25FBโU+25FE. The block has sixteen Variant form (Unicode), standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji.
