CP850
Code page 850 (CCSID 850) (also known as CP 850, IBM 00850, OEM 850, DOS Latin 1) is a code page used under DOS and Psion (company), Psion's EPOC (operating system)#EPOC16, EPOC16 operating systems in Western Europe. Depending on the country setting and system configuration, code page 850 is the primary code page and default OEM code page in many countries, including various English-speaking locales (e.g. in the United Kingdom, Ireland, and Canada), whilst other English-speaking locales (like the United States) default to use the hardware code page code page 437, 437. Code page 850 differs from code page 437 in that many of the box-drawing characters, Greek alphabet, Greek letters, and various symbols were replaced with additional Latin letters with diacritics, thus greatly improving support for Western European languages (all characters from ISO 8859-1 are included). At the same time, the changes frequently caused display glitches with programs that made use of the box-drawing c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Latin Character Sets (computing)
Several binary representations of 8-bit character sets for common Western European languages are compared in this article. These encodings were designed for representation of Italian, Spanish, Portuguese, French, German, Dutch, English, Danish, Swedish, Norwegian, and Icelandic, which use the Latin alphabet, a few additional letters and ones with precomposed diacritics, some punctuation, and various symbols (including some Greek letters). Although they're called "Western European" many of these languages are spoken all over the world. Also, these character sets happen to support many other languages such as Malay, Swahili, and Classical Latin. ''This material is technically obsolete, having been functionally replaced by Unicode. However it continues to have historical interest.'' Summary The ISO-8859 series of 8-bit character sets encodes all Latin character sets used in Europe, albeit that the same code points have multiple uses that caused some difficulty (including mojiba ...

Code Page 858
Code page 858 (CCSID 858) (also known as CP 858, IBM 00858, OEM 858) is a code page used under DOS to write Western European languages. Similarly to code page 850, code page 858 supports the entire repertoire of ISO 8859-1, but in a different arrangement. Code page 858 was created from code page 850 in 1998 by changing code point 213 (D5hex) from dotless i (ı) (a character not included in ISO-8859-1) to the euro sign (€). Unlike most code pages modified to support the euro sign, the generic currency sign at CFhex (an ISO-8859-1 character, changed to the euro sign in ISO-8859-15) was not chosen as the character to replace. Still, instead of adding support for the new code page 858, IBM's PC DOS 2000, also released in 1998, changed the definition of the existing code page 850 to what IBM called ''modified code page 850'' to include the euro sign at code point 213. More recent IBM/MS products implemented codepage 858 under its own ID. Character set The following table ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OEM Code Page
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used. There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages. (ANSI is the American National Standards Institute.) Code pages in both of these groups are extended ASCII code pages. Additional code pages are supported by standard Windows conversion routines, but not used as either type of system code page. ANSI code page ANSI code pages (officially called "Windows code pages" after Microsoft accepted the former term being a misnomer ) are used for native non-Unicode (say, byte oriented) applications using a graphical user interf ...

NBSP
In word processing and digital typesetting, a non-breaking space, , also called NBSP, required space, hard space, or fixed space (though 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 and variations 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 may insert a line break between "100" and "km". An editor who finds this behavior undesirable may choose to use a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraction (mathematics)
A fraction (from la, fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A ''common'', ''vulgar'', or ''simple'' fraction (examples: \tfrac and \tfrac) consists of a numerator, displayed above a line (or before a slash like ), and a non-zero denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not ''common'', including compound fractions, complex fractions, and mixed numerals. In positive common fractions, the numerator and denominator are natural numbers. The numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. The denominator cannot be zero, because zero parts can never make up a whole. For example, in the fraction , the numerator 3 indicates that the ...

Soft Hyphen
In computing and typesetting, a soft hyphen (ISO 8859: 0xAD, Unicode , HTML: ­ or ­ or ­) or syllable hyphen (EBCDIC: 0xCA), abbreviated SHY, is a code point reserved in some coded character sets for the purpose of breaking words across lines by inserting visible hyphens. Two alternative ways of using the soft hyphen character for this purpose have emerged, depending on whether the encoded text will be broken into lines by its recipient, or has already been preformatted by its originator. Text to be formatted by the recipient The use of SHY characters in text that will be broken into lines by the recipient is the application context considered by the post-1999 HTML and Unicode specifications, as well as some word-processing file formats. In this context, the soft hyphen may also be called a discretionary hyphen or optional hyphen. It serves as an invisible marker used to specify a place in text where a hyphenated break is allowed without forcing a line ...

Dotless I
I, or ı, called dotless I, is a letter used in the Latin-script alphabets of Azerbaijani, Crimean Tatar, Gagauz, Kazakh, Tatar, Kyrgyz, and Turkish. It commonly represents the close back unrounded vowel , except in Kazakh where it represents the near-close front unrounded vowel . All of the languages it is used in also use its dotted counterpart İ while not using the basic Latin letter I. In scholarly writing on Turkic languages, ï is sometimes used for . Implications for ligature use In some fonts, if the lowercase letters ''fi'' are placed adjacently, the dot-like upper end of the ''f'' would fall inconveniently close to the dot of the ''i'', and therefore a ligature glyph is provided with the top of the ''f'' extended to serve as the dot of the ''i''. A similar ligature for ''ffi'' is also possible. Since the forms without ligatures are sometimes considered unattractive and the ligatures make the ''i'' dotless, such fonts are not appropriate for use in a Turkish se ...

ISO 8859-1
ISO/IEC 8859-1:1998, ''Information technology — 8-bit single-byte coded graphic character sets — Part 1: Latin alphabet No. 1'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. ISO/IEC 8859-1 encodes what it refers to as "Latin alphabet no. 1", consisting of 191 characters from the Latin script. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is the basis for some popular 8-bit character sets and the first two blocks of characters in Unicode. ISO-8859-1 was (according to the standard, at least) the default encoding of documents delivered via HTTP with a MIME type beginning with "text/" (HTML5 changed this to Windows-1252). , 1.3% of all (but only 8 of the top 1000) web sites use . It is the most ''declared'' single-byte character encoding in the world on the Web, but as Web browsers interpret it as the superset Windows-1252, the documents m ...

4 (number)
4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically 3, three. The sum of the first four prime numbers 2, two + 3, three + 5, five + 7, seven is the only sum of four consecutive prime numbers that yields an Parity (mathematics), odd prime number, 17 (number), seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, 3, three and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...
