TRON (encoding)
TRON Code is a multi-byte character encoding used in the TRON project. It is similar to Unicode but does not use Unicode's Han unification process: each character from each CJK character set is encoded separately, including archaic and historical equivalents of modern characters. This means that Chinese, Japanese, and Korean text can be mixed without any ambiguity as to the exact form of the characters; however, it also means that many characters with equivalent semantics will be encoded more than once, complicating some operations. TRON has room for 150 million code points. Separate code points for Chinese, Korean, and Japanese variants of the 70,000+ Han characters in Unicode 4.1 (if that were deemed necessary) would require more than 200,000 code points in TRON. TRON includes the non-Han characters from Unicode 2.0, but it has not been keeping up to date with recent editions to Unicode as Unicode expands beyond the Basic Multilingual Plane and adds characters to existing scripts ...

TRON Project
TRON (acronym for The Real-time Operating system Nucleus) is an open architecture real-time operating system kernel design. The project was started by Professor Dr. Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs. The Industrial TRON (ITRON) derivative was one of the world's most used operating systems in 2003, being present in billions of electronic devices such as mobile phones, appliances and even cars. Although mainly used by Japanese companies, it garnered interest worldwide. However, a dearth of quality English documentation was said to hinder its broader adoption. The TRON project was integrated into T-Engine Forum in 2010. Today, it is supported by popular Secure Socket Layer (SSL) and Transport Layer Security (TLS) libraries such as wolfSSL. Architecture TRON does not specify the source code for the kernel, but instead is a "set of interfaces and design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Multilingual Plane
In the Unicode standard, a plane is a continuous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+''hhhhhh''). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version , five of the planes have assigned code points (characters), and seven are named. The limit of 17 planes is due to UTF-16, which can encode 220 code points (16 planes) as pairs of words, plus the BMP as a single word. UTF-8 was designed with a much larger limit of 231 (2,147,483,648) code points (32,768 planes), and would still be able to encode 221 (2,097,152) code points (32 planes) even under the current limit of 4 bytes. The 17 planes can accommodate 1,114,1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BTRON
BTRON (Business TRON) is one of the subprojects of the TRON Project proposed by Ken Sakamura, which is responsible for the business phase. It refers to the operating systems (OS), keyboards, peripheral interface specifications, and other items related to personal computers (PCs) that were developed there. Originally, it refers to specifications rather than specific products, but in reality, the term "BTRON" is often used to refer to implementations. Currently, Personal Media Corporation's B-right/V is an implementation of BTRON3, and a software product called "" that includes it has been released. Specifications As with other TRON systems, only the specification of BTRON has been formulated, and the implementation method is not specified. Implementation is mentioned in this section to the extent necessary to explain the specification, but please refer to the Implementation section for details. BTRON1, BTRON2, BTRON3 The BTRON project began with Matsushita Electric Industrial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mojikyō
( ja, 文字鏡), also known by its full name , is a character encoding scheme. The , which published the character set, also published computer software and TrueType fonts to accompany it. The Mojikyō Institute, chaired by , originally had its character set and related software and data redistributed on CD-ROMs sold in Kinokuniya stores. Conceptualized in 1996, the first version of the CD-ROM was released in July 1997. For a time, the Mojikyō Institute also offered a web subscription, termed " WEB" (), which had more up-to-date characters. , ''Mojikyō'' encoded 174,975 characters. Among those, 150,366 characters (\approx86%) then belonged to the extended Chinese–Japanese–Korean–Vietnamese (CJKV)For Korean, Hanja are referred to. For Vietnamese, Chữ Nôm. family. Many of ''Mojikyō'''s characters are considered obsolete or obscure, and are not encoded by any other character set, including the most widely used international text encoding standard, Unicode.

Hentaigana
In the Japanese writing system, are variant forms of hiragana. History Today, with few exceptions, there is only one hiragana for each of the forty-five moras that are written without diacritics or digraphs. However, traditionally there were generally several more-or-less interchangeable hiragana for each. A 1900 script reform ordained that only one selected character be used for each mora, with the rest deemed ''hentaigana''. Today, although not normally used in publication, ''hentaigana'' are still used in shop signs and brand names to create a traditional or antiquated air. Hiragana originate in ''man'yōgana,'' a system where kanji were used to write sounds without regard to their meaning. There was more than one kanji that could be used equivalently for each syllable (at the time, a syllable was a mora). Over time the ''man'yōgana'' was reduced to a cursive form, the hiragana. Many ''hentaigana'' derive from different kanji from the ones for the now-standard hir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braille
Braille (Pronounced: ) is a tactile writing system used by people who are visually impaired, including people who are Blindness, blind, Deafblindness, deafblind or who have low vision. It can be read either on Paper embossing, embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first Binary numeral system, binary form of writing developed in the modern era. Braille characters are formed using a ...

Character Encodings In HTML
While Hypertext Markup Language (HTML) has been in use since 1991, HTML 4.0 from December 1997 was the first standardized version where international characters were given reasonably complete treatment. When an HTML document includes special characters outside the range of seven-bit ASCII, two goals are worth considering: the information's integrity, and universal browser display. Specifying the document's character encoding There are two general ways to specify which character encoding is used in the document. First, the web server can include the character encoding or "charset" in the Hypertext Transfer Protocol (HTTP) Content-Type header, which would typically look like this: Content-Type: text/html; charset=utf-8 This method gives the HTTP server a convenient way to alter document's encoding according to content negotiation; certain HTTP server software can do it, for example Apache with the module mod_charset_lite. Second, a declaration can be included within the docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dongba Symbols
The Dongba, Tomba or Tompa or Mo-so symbols are a system of pictographic glyphs used by the '' ²dto¹mba'' (Bon priests) of the Naxi people in southern China. In the Naxi language it is called ''²ss ³dgyu'' 'wood records' or ''²lv ³dgyu'' 'stone records'.He, 292 "They were developed in approximately the seventh century." The glyphs may be used as rebuses for abstract words which do not have glyphs. Dongba is largely a mnemonic system, and cannot by itself represent the Naxi language; different authors may use the same glyphs with different meanings, and it may be supplemented with the ''geba'' syllabary for clarification. Origin and development The Dongba script appears to be an independent ancient writing system, though presumably it was created in the environment of older scripts. According to Dongba religious fables, the Dongba script was created by the founder of the Bön religious tradition of Tibet, Tönpa Shenrab (Tibetan: ''ston pa gshen rab)'' or Shenrab Miwo (T ...

ISO/IEC 2022
ISO/IEC 2022 ''Information technology—Character code structure and extension techniques'', is an ISO/IEC standard (equivalent to the ECMA standard ECMA-35, the ANSI standard ANSI X3.41 and the Japanese Industrial Standard JIS X 0202) in the field of character encoding. Originating in 1971, it was most recently revised in 1994. ISO 2022 specifies a general structure which character encodings can conform to, dedicating particular ranges of bytes ( 0x00–1F and 0x7F–9F) to be used for non-printing control codes for formatting and in-band instructions (such as line breaks or formatting instructions for text terminals), rather than graphical characters. It also specifies a syntax for escape sequences, multiple-byte sequences beginning with the control code, which can likewise be used for in-band instructions. Specific sets of control codes and escape sequences designed to be used with ISO 2022 include ISO/IEC 6429, portions of which are implemented by ANSI.SYS and terminal emu ...

CJK Characters
In internationalization, CJK characters is a collective term for the Chinese, Japanese, and Korean languages, all of which include Chinese characters and derivatives in their writing systems, sometimes paired with other scripts. Collectively, the CJK characters often include ''Hànzì'' in Chinese, ''Kanji'' and ''Kana'' in Japanese, ''Hanja'' and ''Hangul'' in Korean. Vietnamese can be included, making the abbreviation CJKV, as Vietnamese historically used Chinese characters in which they were known as ''Chữ Hán'' and ''Chữ Nôm'' in Vietnamese ('' Hán-Nôm'' altogether). Character repertoire Standard Mandarin Chinese and Standard Cantonese are written almost exclusively in Chinese characters. Over 3,000 characters are required for general literacy, with up to 40,000 characters for reasonably complete coverage. Japanese uses fewer characters—general literacy in Japanese can be expected with 2,136 characters. The use of Chinese characters in Korea is increasingly rare, a ...
