Code Page 942
Code page 942 (abbreviated as CP942 or IBM-942) is one of IBM's extensions of Shift JIS. The coded character sets are JIS X 0201, JIS X 0208, IBM extensions for IBM 1880 UDC and IBM extensions. It is the combination of the single-byte Code page 1041 and the double-byte Code page 301. It is a superset of IBM-932, differing in its use of Code page 1041 in place of Code page 897 for its single byte codes. Code page 1041 is an extension of Code page 897 and adds five single-byte characters. 0x80 is mapped to the cent sign (¢), 0xA0 is mapped to the pound sign (£), 0xFD is mapped to the not sign (¬), 0xFE is mapped to the backslash (\) and 0xFF is mapped to the tilde (~). These are all unassigned in Code page 897 and therefore IBM-932. Code page 942 contains standard 7-bit ISO 646 codes, and Japanese characters are indicated by the high bit of the first byte being set to 1. Some code points in this page require a second byte, so characters use either 8 or 16 bits for encoding. Cod ...

Code Page
In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte. (In some contexts these terms are used more precisely; see .) The term "code page" originated from IBM's EBCDIC-based mainframe systems, but Microsoft, SAP, and Oracle Corporation are among the vendors that use this term. The majority of vendors identify their own character sets by a name. In the case when there is a plethora of character sets (like in IBM), identifying character sets through a number is a convenient way to distinguish them. Originally, the code page numbers referred to the ''page'' numbers in the IBM standard character set manual, a condition which has not held for a long time. Vendors that use a code page system allocate their own code page number to a character encoding, even if it is better known by another name; for example, U ...

Backslash
The backslash is a typographical mark used mainly in computing and mathematics. It is the mirror image of the common slash . It is a relatively recent mark, first documented in the 1930s. History , efforts to identify either the origin of this character or its purpose before the 1960s have not been successful. The earliest known reference found to date is a 1937 maintenance manual from the Teletype Corporation with a photograph showing the keyboard of its Kleinschmidt keyboard perforator WPE-3 using the Wheatstone system. The symbol was called the "diagonal key", and given a (non-standard) Morse code of . (This is the code for the slash symbol, entered backwards.) In June 1960, IBM published an "Extended character set standard" that includes the symbol at 0x19.

In September 1961, Bob Bemer (IBM) proposed to the X3.2 standards committee that ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Code Page 943
Microsoft Windows code page 932 (abbreviated MS932, Windows-932 or ambiguously CP932), also called Windows-31J amongst other names (see § Terminology below), is the Microsoft Windows code page for the Japanese language, which is an extended variant of the Shift JIS Japanese character encoding. It contains standard 7-bit ASCII codes, and Japanese characters are indicated by the high bit of the first byte being set to 1. Some code points in this page require a second byte, so characters use either 8 or 16 bits for encoding. IBM offer the same extended double-byte codes in their code page 943 (IBM-943 or CP943), which is a combination of the single-byte Code page 897 and the double-byte Code page 941. Windows-31J is the most used non-UTF-8/Unicode Japanese encoding on the web. Actually is the much more declared encoding, but by W3C/WHATWG HTML standards, the encodings are declared the same, and while the latter name is used in the standards it's defined to decode the former.

US-ASCII
ASCII ( ), abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are , which severely limited its scope. All modern computer systems instead use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set. The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding. ASCII is one of the IEEE milestones. Overview ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American National Standards Institut ...

Yen Sign
The yen and yuan sign, ¥, is a currency sign used for the Japanese yen and the Renminbi, Chinese yuan currency, currencies when writing in Latin scripts. This monetary symbol resembles a Latin letter Y with a single or double horizontal stroke. The symbol is usually placed before the value it represents, for example: ¥50, or JP¥50 and CN¥50 when disambiguation is needed. When writing in Japanese and Chinese, the Japanese kanji and Chinese character is written following the amount, for example in Japan, and or in China. Code points The Unicode code point is . Additionally, there is a Full-width, full width character, , at code point for use with wide fonts, especially East Asian fonts. There was no code-point for this symbol in the original (7-bit) US-ASCII and consequently many early systems reassigned (allocated to the backslash (\) in ASCII) to the yen sign. With the arrival of 8-bit encoding, the ISO/IEC 8859-1 ("ISO Latin 1") character set assigned code point to ...

ISO 646
ISO/IEC 646 is a set of ISO/IEC standards, described as ''Information technology — ISO 7-bit coded character set for information interchange'' and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived. ISO/IEC 646 was also ratified by ECMA as ECMA-6. The first version of ECMA-6 had been published in 1965, based on work the ECMA's Technical Committee TC1 had carried out since December 1960. Characters in the ISO/IEC 646 Basic Character Set are ''invariant characters''. Since that portion of ISO/IEC 646, that is the ''invariant character set'' shared by all countries, specified only those letters used in the ISO basic Latin alphabet, countries using additional letters needed to create national variants of ISO/IEC 646 to be able to use their native scripts. Since transmission and storage of 8-bit codes was not standard at the time ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tilde
The tilde () or , is a grapheme with several uses. The name of the character came into English from Spanish, which in turn came from the Latin '' titulus'', meaning "title" or "superscription". Its primary use is as a diacritic (accent) in combination with a base letter; but for historical reasons, it is also used in standalone form within a variety of contexts. History Use by medieval scribes The tilde was originally written over an omitted letter or several letters as a scribal abbreviation, or "mark of suspension" and "mark of contraction", shown as a straight line when used with capitals. Thus, the commonly used words ''Anno Domini'' were frequently abbreviated to ''Ao Dñi'', with an elevated terminal with a suspension mark placed over the "n". Such a mark could denote the omission of one letter or several letters. This saved on the expense of the scribe's labor and the cost of vellum and ink. Medieval European charters written in Latin are largely made up of such ab ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Not Sign
In logic, negation, also called the logical complement, is an operation that takes a proposition P to another proposition "not P", written \neg P, \mathord P or \overline. It is interpreted intuitively as being true when P is false, and false when P is true. Negation is thus a unary logical connective. It may be applied as an operation on notions, propositions, truth values, or semantic values more generally. In classical logic, negation is normally identified with the truth function that takes ''truth'' to ''falsity'' (and vice versa). In intuitionistic logic, according to the Brouwer–Heyting–Kolmogorov interpretation, the negation of a proposition P is the proposition whose proofs are the refutations of P. Definition ''Classical negation'' is an operation on one logical value, typically the value of a proposition, that produces a value of ''true'' when its operand is false, and a value of ''false'' when its operand is true. Thus if statement is true, then \neg P (pro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shift JIS
Shift JIS (Shift Japanese Industrial Standards, also SJIS, MIME name Shift_JIS, known as PCK in Solaris contexts) is a character encoding for the Japanese language, originally developed by a Japanese company called ASCII Corporation in conjunction with Microsoft and standardized as JIS X 0208 Appendix 1. , 0.2% of all web pages used Shift JIS, a decline from 1.3% in July 2014. Shift JIS is the second-most popular character encoding for Japanese websites, used by 5.6% of sites in the .jp domain. UTF-8 is used by 94.4% of Japanese websites. Description Shift JIS is based on character sets defined within JIS standards (for the single-byte characters) and (for the double-byte characters). The lead bytes for the double-byte characters are "shifted" around the 64 halfwidth katakana characters in the single-byte range 0xA1 to 0xDF. The single-byte characters 0x00 to 0x7F match the ASCII encoding, except for a yen sign (U+00A5) at 0x5C and an overline (U+203E) at 0x7E in place of ...

Cent Sign
The cent is a monetary unit of many national currencies that equals of the basic monetary unit. Etymologically, the word 'cent' derives from the Latin word meaning hundred. The cent sign is commonly a simple minuscule (lower case) letter . In North America, the c is crossed by a diagonal stroke or a vertical line (depending on typeface), yielding the character . The United States one cent coin is generally known by the nickname "penny", alluding to the British coin and unit of that name. Australia ended production of their 1¢ coin in 1992, as did Canada in 2012. Some Eurozone countries ended production of the 1 euro cent coin, most recently Italy in 2018. Symbol The cent may be represented by the cent sign, written in various ways according to the national convention and font choice. Most commonly seen forms are a minuscule letter ''c'' crossed by a diagonal stroke or a vertical line or by a simple ''c'', depending on the currency (''see below''). Cent amounts from ...

Code Page 897
Code page 897 (CCSID 897) is IBM's implementation of the 8-bit form of JIS X 0201. It includes several additional graphical characters in the C0 control characters area, and the code points in question may be used as control characters or graphical characters depending on the context, similarly in concept to OEM-US, but with different graphical characters. The C0 rows are shown below. Amongst IBM's code pages, it accompanies code page 895, which encodes the ISO 646 set of JIS X 0201, and code page 896 (half-width katakana), which encodes the Kana set (upper half) of JIS X 0201 with extensions. When combined with the double-byte code page 301, it makes up the two code-sets of IBM code page 932 (IBM PC Japan MIX). When combined with the double-byte code page 941, it makes up code page 943 (equivalent to Windows-932, although Microsoft uses ASCII mappings for 0x00 though 0x7F). When combined with the double-byte code page 1393, it makes up code page 1394. Codepage layout C ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
