Word Joiner
The word joiner (WJ) is a Unicode format character (computing), character which is used to indicate that line breaking should not occur at its position. It does not affect the formation of Ligature (writing), ligatures or cursive joining and is ignored for the purpose of text segmentation. It is encoded since Unicode version 3.2 (released in 2002) as . The word joiner replaces the ''zero-width no-break space'' (''ZWNBSP'', U+FEFF), as a usage of the no-break space of zero width. The ''ZWNBSP'' is originally and currently used as the byte order mark (BOM) at the start of a file. However, if encountered elsewhere, it should, according to Unicode, be treated as a word joiner, a non-breaking space, no-break space of zero width. The deliberate use of U+FEFF for this purpose is deprecated as of Unicode 3.2, with the ''word joiner'' strongly preferred. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Character (computing)
In computing and telecommunications, a character is the internal representation of a character (symbol) used within a computer or system. Examples of characters include letters, numerical digits, punctuation marks (such as "." or "-"), and whitespace. The concept also includes control characters, which do not correspond to visible symbols but rather to instructions to format or process the text. Examples of control characters include carriage return and tab as well as other instructions to printers or other devices that display or otherwise process text. Characters are typically combined into '' strings''. Historically, the term ''character'' was used to denote a specific number of contiguous bits. While a character is most commonly assumed to refer to 8 bits (one byte) today, other options like the 6-bit character code were once popular, and the 5-bit Baudot code has been used in the past as well. The term has even been applied to 4 bits with only 16 possible valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Breaking
Text wrapping, also known as line wrapping, word wrapping or line breaking, is breaking a section of text into lines so that it will fit into the available width of a page, window or other display area. In text display, line wrap is continuing on a new line when a line is full, so that each line fits into the viewable area without overflowing, allowing text to be read from top to bottom without any horizontal scrolling. Word wrap is the additional feature of most text editors, word processors, and web browsers, of breaking lines between words rather than within words, where possible. Word wrap makes it unnecessary to hard-code newline delimiters within paragraphs, and allows the display of text to adapt flexibly and dynamically to displays of varying sizes. Examples Soft and hard returns A soft return or soft wrap is the break resulting from line wrap or word wrap (whether automatic or manual), whereas a hard return or hard wrap is an intentional break, creating a new pa ...

Ligature (writing)
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 prolife ...

Cursive
Cursive (also known as joined-up writing) is any style of penmanship in which characters are written joined in a flowing manner, generally for the purpose of making writing faster, in contrast to block letters. It varies in functionality and modern-day usage across languages and regions; being used both publicly in artistic and formal documents as well as in private communication. Formal cursive is generally joined, but casual cursive is a combination of joins and pen lifts. The writing style can be further divided as "looped", "italic script, italic", or "connected". The cursive method is used with many alphabets due to infrequent pen lifting which allows increased writing speed. However, more elaborate or ornamental calligraphic styles of writing can be slower to reproduce. In some alphabets, many or all letters in a word are connected, sometimes making a word one single complex stroke. History Cursive is a style of penmanship in which the symbols of the language are writt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byte Order Mark
The byte-order mark (BOM) is a particular usage of the special Unicode character code, , whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: * the byte order, or endianness, of the text stream in the cases of 16- bit and 32-bit encodings; * the fact that the text stream's encoding is Unicode, to a high level of confidence; * which Unicode character encoding is used. BOM use is optional. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream. Unicode can be encoded in units of 8-bit, 16-bit, or 32-bit integers. For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. The BOM is encoded in the same scheme as the rest of the document and becomes a Unicode code point if its bytes are swapped. Hence, the process ...

Non-breaking Space
In word processing and digital typesetting, a non-breaking space (), also called NBSP, required space, hard space, or fixed space (in most typefaces, it is not of fixed width), is a space character that prevents an automatic line break at its position. In some formats, including HTML, it also prevents consecutive whitespace characters from collapsing into a single space. Non-breaking space characters with other widths also exist. Uses Despite having layout and uses similar to those of whitespace, it differs in contextual behavior. Non-breaking behavior Text-processing software typically assumes that an automatic line break may be inserted anywhere a space character occurs; a non-breaking space prevents this from happening (provided the software recognizes the character). For example, if the text "100 km" will not quite fit at the end of a line, the software ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zero-width Space
The zero-width space (rendered: ; HTML entity: or ), abbreviated ZWSP, is a control character, non-printing character used in computerized typesetting to indicate where the word boundaries are, without actually displaying a visible space in the rendered text. This enables text-processing systems for scripts that do not use explicit spacing to recognize where word boundaries are for the purpose of handling line wrap and word wrap, line breaks appropriately. The zero-width space is Unicode character U+200B, and is located in the Unicode General Punctuation block. In HTML, it can be represented by the character entity reference . Purpose The zero-width space marks a potential line break without syllabification, hyphenation. Its semantics and HyperText Markup Language, HTML implementation are similar to the soft hyphen, but soft hyphens display a hyphen character at the point where the line is broken. The zero-width space can be used to mark word breaks in languages without visible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero-width Joiner
The zero-width joiner (ZWJ, ; rendered: ; HTML entity: or ) is a non-printing character used in the computerized typesetting of writing systems in which the shape or positioning of a grapheme depends on its relation to other graphemes (complex scripts), such as the Arabic script or any Indic script. Sometimes the Latin script, Roman script is to be counted as complex, e.g. when using a Fraktur typeface. When placed between two characters that would otherwise not be connected, a ZWJ causes them to be printed in their connected forms. The exact behaviour of the ZWJ varies depending on whether the use of a conjunct consonant or ligature (where multiple characters are shown with a single glyph) is expected by default; for instance, it suppresses the use of conjuncts in Devanagari (whilst still allowing the use of the individual joining form of a dead consonant, as opposed to a halant form as would be required by the zero-width non-joiner), but induces the use of Sinhala script#Cons ...

Control Characters
In computing and telecommunications, a control character or non-printing character (NPC) is a code point in a character set that does not represent a written character or symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text. All other characters are mainly '' graphic characters'', also known as ''printing characters'' (or ''printable characters''), except perhaps for "space" characters. In the ASCII standard there are 33 control characters, such as code 7, , which rings a terminal bell. History Procedural signs in Morse code are a form of control character. A form of control characters were introduced in the 1870 Baudot code: NUL and DEL. The 1901 Murray code added the carriage return (CR) and line feed (LF), and other versions of the Baudot code included other control characters. The bell character (BEL), which rang a bell to alert operators, was also an early teletype control character. Some control character ...
