Unicode Block
A Unicode block is one of several contiguous ranges of numeric character codes ( code points) of the Unicode character set that are defined by the Unicode Consortium for administrative and documentation purposes. Typically, proposals such as the addition of new glyphs are discussed and evaluated by considering the relevant block or blocks as a whole. Each block is generally, but not always, meant to supply glyphs used by one or more specific languages, or in some general application area such as mathematics, surveying, decorative typesetting, social forums, etc. Design and implementation Unicode blocks are identified by unique names, which use only ASCII characters and are usually descriptive of the nature of the symbols, in English; such as "Tibetan" or "Supplemental Arrows-A". (When comparing block names, one is supposed to equate uppercase with lowercase letters, and ignore any whitespace, hyphens, and underbars; so the last name is equivalent to "supplemental_arrows__a" a ...

Code Point
In character encoding terminology, a code point, codepoint or code position is a numerical value that maps to a specific character. Code points usually represent a single grapheme—usually a letter, digit, punctuation mark, or whitespace—but sometimes represent symbols, control characters, or formatting. The set of all possible code points within a given encoding/character set make up that encoding's ''codespace''. For example, the character encoding scheme ASCII comprises 128 code points in the range 0 hex to 7Fhex, Extended ASCII comprises 256 code points in the range 0hex to FFhex, and Unicode comprises code points in the range 0hex to 10FFFFhex. The Unicode code space is divided into seventeen planes (the basic multilingual plane, and 16 supplementary planes), each with (= 216) code points. Thus the total size of the Unicode code space is 17 × = . Definition The notion of a code point is used for abstraction, to distinguish both: * the numbe ...

Hangul
The Korean alphabet, known as Hangul, . Hangul may also be written as following South Korea's standard Romanization. ( ) in South Korea and Chosŏn'gŭl in North Korea, is the modern official writing system for the Korean language. The letters for the five basic consonants reflect the shape of the speech organs used to pronounce them, and they are systematically modified to indicate phonetic features; similarly, the vowel letters are systematically modified for related sounds, making Hangul a featural writing system. It has been described as a syllabic alphabet as it combines the features of alphabetic and syllabic writing systems, although it is not necessarily an abugida. Hangul was created in 1443 CE by King Sejong the Great in an attempt to increase literacy by serving as a complement (or alternative) to the logographic Sino-Korean '' Hanja'', which had been used by Koreans as its primary script to write the Korean language since as early as the Gojoseon pe ...

Hangul Syllables
Hangul Syllables is a Unicode block containing precomposed Hangul syllable blocks for modern Korean. The syllables can be directly mapped by algorithm to sequences of two or three characters in the Hangul Jamo Unicode block: * one of U+1100–U+1112: the 19 modern Hangul leading consonant jamos; * one of U+1161–U+1175: the 21 modern Hangul vowel jamos; * none, or one of U+11A8–U+11C2: the 27 modern Hangul trailing consonant jamos. This block is encoded according to the canonically equivalent order of these (two or three) jamos (one in each subrange of jamos above) composing each syllable. Note that a full Hangul syllable may include one of these characters but may be preceded by one or more leading consonant jamos, and followed by one or more trailing jamos (possibly preceded by one or more vowel jamos if the encoded syllable is composed by two jamos does not include any trailing consonant jamos). As well some Hangul syllables may not include any one of these precomposed c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hangul (obsolete Unicode Block)
Hangul, Hangul Supplementary-A, and Hangul Supplementary-B were character blocks that existed in Unicode 1.0 and 1.1, and ISO/IEC 10646-1:1993. These blocks encoded precomposed modern Hangul syllables. These three Unicode 1.x blocks were deleted and superseded by the new Hangul Syllables block (U+AC00–U+D7AF) in Unicode 2.0 (July 1996) and ISO/IEC 10646-1:1993 Amd. 5 (1998), and are now occupied by CJK Unified Ideographs Extension A and Yijing Hexagram Symbols. Moving or removing existing characters has been prohibited by the Unicode Stability Policy for all versions following Unicode 2.0, so the Hangul Syllables block introduced in Unicode 2.0 is immutable. Documentation The Unicode 1.0.0 code chart is still available online, including the Korean Hangul Syllables block, but not the supplements added in Unicode 1.1. Full code charts for Unicode 1.1 were "never created", since Unicode 1.1 was published only as a report amending Unicode 1.0 due to the urgency of releasing it; howe ...

Tibetan Script
The Tibetan script is a segmental writing system (''abugida'') of Indic origin used to write certain Tibetic languages, including Tibetan, Dzongkha, Sikkimese, Ladakhi, Jirel and Balti. It has also been used for some non-Tibetic languages in close cultural contact with Tibet, such as Thakali. The printed form is called uchen script while the hand-written cursive form used in everyday writing is called umê script. This writing system is used across the Himalayas, and Tibet. The script is closely linked to a broad ethnic Tibetan identity, spanning across areas in India, Nepal, Bhutan and Tibet. The Tibetan script is of Brahmic origin from the Gupta script and is ancestral to scripts such as Meitei, Lepcha,Daniels, Peter T. and William Bright. ''The World's Writing Systems''.

Tibetan (Unicode Block)
Tibetan is a Unicode block containing characters for the Tibetan, Dzongkha, and other languages of China, Bhutan, Nepal, Mongolia, northern India, eastern Pakistan and Russia. Block Former Tibetan block The Tibetan Unicode block is unique for having been allocated in version 1.0.0 with a virama-based encoding that was unable to distinguish visible and conjunct consonant correctly. This encoding was removed from the Unicode Standard in version 1.0.1 in the process of unifying with ISO 10646 for version 1.1, then reintroduced as an explicit root/subjoined encoding, with a larger block size, in version 2.0. Moving or removing existing characters has been prohibited by the Unicode Stability Policy for all versions following Unicode 2.0, so the Tibetan characters encoded in Unicode 2.0 and all subsequent versions are immutable.

Script (Unicode)
In Unicode, a script is a collection of letters and other written signs used to represent textual information in one or more writing systems. Some scripts support one and only one writing system and language, for example, Armenian. Other scripts support many different writing systems; for example, the Latin script supports English, French, German, Italian, Vietnamese, Latin itself, and several other languages. Some languages make use of multiple alternate writing systems and thus also use several scripts; for example, in Turkish, the Arabic script was used before the 20th century but transitioned to Latin in the early part of the 20th century. For a list of languages supported by each script, see the list of languages by writing system. More or less complementary to scripts are symbols and Unicode control characters. The unified diacritical characters and unified punctuation characters frequently have the "common" or "inherited" script property. However, the individual s ...

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 o ...
