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 ...

Windows-31J
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.

Variable-width Encoding
A variable-width encoding is a type of character encoding scheme in which codes of differing lengths are used to encode a character set (a repertoire of symbols) for representation, usually in a computer. Most common variable-width encodings are multibyte encodings, which use varying numbers of bytes ( octets) to encode different characters. (Some authors, notably in Microsoft documentation, use the term ''multibyte character set,'' which is a misnomer, because representation size is an attribute of the encoding, not of the character set.) Early variable width encodings using less than a byte per character were sometimes used to pack English text into fewer bytes in adventure games for early microcomputers. However disks (which unlike tapes allowed random access allowing text to be loaded on demand), increases in computer memory and general purpose compression algorithms have rendered such tricks largely obsolete. Multibyte encodings are usually the result of a need to increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenSolaris
OpenSolaris () is a discontinued open-source computer operating system based on Solaris and created by Sun Microsystems. It was also, perhaps confusingly, the name of a project initiated by Sun to build a developer and user community around the eponymous operating system software. OpenSolaris is a descendant of the UNIX System V Release 4 (SVR4) code base developed by Sun and AT&T in the late 1980s and is the only version of the System V variant of UNIX available as open source. OpenSolaris was developed as a combination of several software ''consolidations'' that were open sourced starting with Solaris 10. It includes a variety of free software, including popular desktop and server software. After Oracle’s acquisition of Sun Microsystems in 2010, Oracle discontinued development of OpenSolaris in house, pivoting to focus exclusively on the development of the proprietary Solaris Express (now Oracle Solaris). Prior to Oracle's close-sourcing Solaris, a group of former O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASCII Corporation
was a Japanese publishing company based in Chiyoda, Tokyo. It became a subsidiary of Kadokawa Group Holdings in 2004, and merged with another Kadokawa subsidiary MediaWorks (publisher), MediaWorks on April 1, 2008, becoming ASCII Media Works. The company published ''ASCII (magazine), Monthly ASCII'' as the main publication. ASCII is best known for creating the ''Derby Stallion'' video game series, the MSX computer, and the ''RPG Maker'' line of programming software. History 1977–1990: Founding and first projects ASCII was founded in 1977 by Kazuhiko Nishi and Keiichiro Tsukamoto. Originally the publisher of a magazine with the same name, ''ASCII (magazine), ASCII'', talks between Bill Gates and Nishi led to the creation of Microsoft, Microsoft's first overseas sales office, ASCII Microsoft, in 1978.Quote from Bill Gates' ''The Road Ahead'', found in In 1980, ASCII made 1.2 billion yen of sales from licensing Microsoft BASIC. It was 40 percent of Microsoft's sales, and Nishi b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

String Literal
A string literal (computer programming), literal or anonymous string is a String (computer science), string value in the source code of a computer program. Modern Computer programming, programming languages commonly use a quoted sequence of characters, formally "#Bracketed delimiters, bracketed delimiters", as in x = "foo", where "foo" is a string Literal (computer programming), literal with value foo. Methods such as #Escape sequences, escape sequences can be used to avoid the problem of #Delimiter collision, delimiter collision (issues with brackets) and allow the delimiters to be embedded in a string. There are many alternate notations for specifying string literals especially in complicated cases. The exact notation depends on the programming language in question. Nevertheless, there are general guidelines that most modern programming languages follow. Syntax Bracketed delimiters Most modern programming languages use delimiter#Bracket delimiters, bracket delimiters (also ba ...

Overline
An overline, overscore, or overbar, is a typographical feature of a horizontal line drawn immediately above the text. In old mathematical notation, an overline was called a '' vinculum'', a notation for grouping symbols which is expressed in modern notation by parentheses, though it persists for symbols under a radical sign. The original use in Ancient Greek was to indicate compositions of Greek letters as Greek numerals. In Latin, it indicates Roman numerals multiplied by a thousand and it forms medieval abbreviations (sigla). Marking one or more words with a continuous line above the characters is sometimes called ''overstriking'', though overstriking generally refers to printing one character on top of an already-printed character. An overline, that is, a single line above a chunk of text, should not be confused with the macron, a diacritical mark placed above (or sometimes below) ''individual'' letters. The macron is narrower than the character box. Uses Medicine In most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Yen
The is the official currency of Japan. It is the third-most traded currency in the foreign exchange market, after the United States dollar (US$) and the euro. It is also widely used as a third reserve currency after the US dollar and the euro. The New Currency Act of 1871 introduced Japan's modern currency system, with the yen defined as of gold, or of silver, and divided decimally into 100 ''sen'' or 1,000 ''rin''. The yen replaced the previous Tokugawa coinage as well as the various ''hansatsu'' paper currencies issued by feudal ''han'' (fiefs). The Bank of Japan was founded in 1882 and given a monopoly on controlling the money supply. Following World War II, the yen lost much of its prewar value. To stabilize the Japanese economy, the exchange rate of the yen was fixed at ¥360 per US$ as part of the Bretton Woods system. When that system was abandoned in 1971, the yen became undervalued and was allowed to float. The yen had appreciated to a peak of ¥271 per 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 List of IEEE milestones, 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 Nat ...

Hexadecimal
In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, a number of ...

Katakana
is a Japanese syllabary, one component of the Japanese writing system along with hiragana, kanji and in some cases the Latin script (known as rōmaji). The word ''katakana'' means "fragmentary kana", as the katakana characters are derived from components or fragments of more complex kanji. Katakana and hiragana are both kana systems. With one or two minor exceptions, each syllable (strictly mora) in the Japanese language is represented by one character or ''kana'' in each system. Each kana represents either a vowel such as "''a''" (katakana ア); a consonant followed by a vowel such as "''ka''" (katakana カ); or "''n''" (katakana ン), a nasal sonorant which, depending on the context, sounds either like English ''m'', ''n'' or ''ng'' () or like the nasal vowels of Portuguese or Galician. In contrast to the hiragana syllabary, which is used for Japanese words not covered by kanji and for grammatical inflections, the katakana syllabary usage is comparable to italics in En ...

Double-byte Character
A double-byte character set (DBCS) is a character encoding in which either all characters (including control characters) are encoded in two bytes, or merely every graphic character not representable by an accompanying single-byte character set (SBCS) is encoded in two bytes (Han characters would generally comprise most of these two-byte characters). A DBCS supports national languages that contain many unique characters or symbols (the maximum number of characters that can be represented with one byte is 256 characters, while two bytes can represent up to 65,536 characters). Examples of such languages include Japanese and Chinese. Korean Hangul does not contain as many characters, but KS X 1001 supports both Hangul and Hanja, and uses two bytes per character. In CJK (Chinese/Japanese/Korean) computing The term ''DBCS'' traditionally refers to a character encoding where each graphic character is encoded in two bytes. In an 8-bit code, such as Big-5 or Shift JIS, a character from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
