Text Editing
A text editor is a type of computer program that edits plain text. An example of such program is "notepad" software (e.g. Windows Notepad). Text editors are provided with operating systems and software development packages, and can be used to change files such as configuration files, documentation files and programming language source code. Plain text and rich text There are important differences between plain text (created and edited by text editors) and rich text (such as that created by word processors or desktop publishing software). Plain text exclusively consists of character representation. Each character is represented by a fixed-length sequence of one, two, or four bytes, or as a variable-length sequence of one to four bytes, in accordance to specific character encoding conventions, such as ASCII, ISO/IEC 2022, Shift JIS, UTF-8, or UTF-16. These conventions define many printable characters, but also non-printing characters that control the flow of the tex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UTF-16
UTF-16 (16-bit Unicode Transformation Format) is a character encoding that supports all 1,112,064 valid code points of Unicode. The encoding is variable-length as code points are encoded with one or two ''code units''. UTF-16 arose from an earlier obsolete fixed-width 16-bit encoding now known as UCS-2 (for 2-byte Universal Character Set), once it became clear that more than 216 (65,536) code points were needed, including most emoji and important CJK characters such as for personal and place names. UTF-16 is used by the Windows API, and by many programming environments such as Java and Qt. The variable length character of UTF-16, combined with the fact that most characters are ''not'' variable length (so variable length is rarely tested), has led to many bugs in software, including in Windows itself. UTF-16 is the only encoding (still) allowed on the web that is incompatible with 8-bit ASCII. However it has never gained popularity on the web, where it is declared by under 0.004 ...

Office Open XML
Office Open XML (also informally known as OOXML) is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations and word processing documents. Ecma International standardized the initial version as ECMA-376. ISO and IEC standardized later versions as ISO/IEC 29500. Microsoft Office 2010 provides read support for ECMA-376, full support for ISO/IEC 29500 Transitional, and read support for ISO/IEC 29500 Strict. Microsoft Office 2013 and later fully support ISO/IEC 29500 Strict, but do not use it as the default file format because of backwards compatibility concerns. Background In 2000, Microsoft released an initial version of an XML-based format for Microsoft Excel, which was incorporated in Office XP. In 2002, a new file format for Microsoft Word followed. The Excel and Word formats—known as the Microsoft Office XML formats—were later incorporated into the 2003 release of Microsoft Office. Microsoft announced in November ...

HTML
Hypertext Markup Language (HTML) is the standard markup language for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript, a programming language. Web browsers receive HTML documents from a web server or from local storage and browser engine, render the documents into multimedia web pages. HTML describes the structure of a web page Semantic Web, semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, HTML element#Images and objects, images and other objects such as Fieldset, interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, Hyperlink, links, quotes, and other items. HTML elements are delineated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rich Text Format
) As an example, the following RTF code would be rendered as follows: This is some bold text. Character encoding A standard RTF file can only consist of 7-bit ASCII characters, but can use escape sequences to encode other characters. The two character escapes are code page escapes and, starting with RTF 1.5, Unicode escapes. In a code page escape, two hexadecimal digits following a backslash and typewriter apostrophe denote a character taken from a Windows code page. For example, if the code page is set to Windows-1256, the sequence \'c8 will encode the Arabic letter ''bāʼ'' ب. It is also possible to specify a "Character Set" in the preamble of the RTF document and associate it to a header. For example, the preamble has the text \f3\fnil\fcharset128, then, in the body of the document, the text \f3\'bd\'f0 will represent the code point 0xbd 0xf0 from the Character Set 128 (which corresponds to the Shift-JIS code page), which encodes "金".

Markup Language
A markup language is a Encoding, text-encoding system which specifies the structure and formatting of a document and potentially the relationships among its parts. Markup can control the display of a document or enrich its content to facilitate automated processing. A markup language is a set of rules governing what markup information may be included in a document and how it is combined with the content of the document in a way to facilitate use by humans and computer programs. The idea and terminology evolved from the "marking up" of paper manuscripts (e.g., with revision instructions by editors), traditionally written with a red pen or blue pencil (editing), blue pencil on authors' manuscripts. Older markup languages, which typically focus on typography and presentation, include Troff, TeX, and LaTeX. Scribe (markup language), Scribe and most modern markup languages, such as Extensible Markup Language, XML, identify document components (for example headings, paragraphs, and tabl ...

Doc (computing)
.doc (an abbreviation of "document") is a filename extension used for word processing documents stored on Microsoft's Proprietary format, proprietary Microsoft Word Binary File Format; it was the primary format for Microsoft Word until the Microsoft Office 2007, 2007 version replaced it with Office Open XML .docx files. Microsoft has used the extension since 1983. Overview Binary file, Binary DOC files often contain more text formatting information (as well as script (computer programming), scripts and undo information) than some other document file formats like Rich Text Format and Hypertext Markup Language, but are usually less widely computer compatibility, compatible. The DOC files created with Microsoft Word versions differ: Word for Windows 1.0 and 2.0 uses a format that was changed in the following Word 6.0 and 95 ("7.0") releases. DOC was changed once again into an Object Linking and Embedding , OLE and Compound File Binary Format , CFBF-based format used from Word 97 ("8 ...

Binary Format
A binary file is a computer file that is not a text file. The term "binary file" is often used as a term meaning "non-text file". Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text, such as older Microsoft Word document files, contain the text of the document but also contain formatting information in binary form. Background and terminology All modern computers store information in the form of bits (binary digits), using binary code. For this reason, all data stored on a computer is, in some sense, "binary". However, one particularly useful and ubiquitous type of data stored on a computer is one in which the bits represent text, by way of a character encoding. Those files are called " text files" and files which are not like that are referred to as "binary files", as a sort of retronym or hypernym. Some "text files" contain portions that are actually binary data, and many "binary file ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Font
In metal typesetting, a font is a particular size, weight and style of a ''typeface'', defined as the set of fonts that share an overall design. For instance, the typeface Bauer Bodoni (shown in the figure) includes fonts " Roman" (or "regular"), "" and ""; each of these exists in a variety of sizes. In the digital description of fonts ( computer fonts), the terms "font" and "typeface" are often used interchangeably. For example, when used in computers, each style is stored in a separate digital font file. In both traditional typesetting and computing, the word "font" refers to the delivery mechanism of an instance of the typeface. In traditional typesetting, the font would be made from metal or wood type: to compose a page may require multiple fonts from the typeface or even multiple typefaces. Spelling and etymology The word ''font'' (US) or ''fount'' (traditional UK, CAN; in any case pronounced ) derives from Middle French ''fonte'', meaning "cast iron". The term re ...

Monospace Font
A monospaced font, also called a fixed-pitch, fixed-width, or non-proportional font, is a font whose letters and characters each occupy the same amount of horizontal space. This contrasts with Typeface#Proportion, variable-width fonts, where the letters and spacings have different widths. Monospaced fonts are customary on typewriters and for typesetting computer code. Monospaced fonts were widely used in early computers and computer terminals, which had limited graphical capabilities. Hardware implementation was simplified by using a text mode where the screen layout was addressed as a regular grid of tiles, each of which could be set to display a character by indexing into the hardware's character map. Some systems allowed colored text to be displayed by varying the foreground and background color for each tile. Other effects included reverse video and blinking text. Nevertheless, these early systems were typically limited to a single Command-line interface, console font ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text File
A text file (sometimes spelled textfile; an old alternative name is flat file) is a kind of computer file that is structured as a sequence of lines of electronic text. A text file exists stored as data within a computer file system. In operating systems such as CP/M, where the operating system does not keep track of the file size in bytes, the end of a text file is denoted by placing one or more special characters, known as an end-of-file (EOF) marker, as padding after the last line in a text file. In modern operating systems such as DOS, Microsoft Windows and Unix-like systems, text files do not contain any special EOF character, because file systems on those operating systems keep track of the file size in bytes. Some operating systems, such as Multics, Unix-like systems, CP/M, DOS, the classic Mac OS, and Windows, store text files as a sequence of bytes, with an end-of-line delimiter at the end of each line. Other operating systems, such as OpenVMS and OS/360 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Page Break
A page break is a marker in an electronic document that tells the document interpreter the content which follows is part of a new page. A page break causes a form feed to be sent to the printer during spooling of the document to the printer. It is one of the elements that contributes to pagination. Form feed Form feed is a page-breaking ASCII control character. It directs the printer to eject the current page and to continue printing at the top of another. It will often also cause a carriage return. The form feed character code is defined as 12 (0xC in hexadecimal), and may be represented as or . In a related use, can be pressed to clear the screen in Unix shells such as bash, or redraw the screen in TUI programs like vi/emacs. In the C programming language (and other languages derived from C), the form feed character is represented as '\f'. Unicode also provides the character as a printable symbol for a form feed (not as the form feed itself). The form feed character is con ...
