The writing system of the Korean language is a syllabic alphabet of character parts organized into character blocks representing syllables. The character parts cannot be written from left to right on the computer, as in many Western languages. Every possible syllable in Korean would have to be rendered as syllable blocks by a font, or each character part would have to be encoded separately. Unicode has both options; the character parts ㅎ (h) and ㅏ (a), and the combined syllable 하 (ha), are encoded.
A whitespace character is a character data element that represents white space when text is rendered for display by a computer.
Unified Hangul Code (UHC), or Extended Wansung, also known under Microsoft Windows as Code Page 949, is the Microsoft Windows code page for the Korean language. It is an extension of Wansung Code to include all 11172 non-partial Hangul syllables present in Johab. This corresponds to the pre-composed syllables available in Unicode 2.0 and later.
New Gulim (새굴림/SaeGulRim) is a sans-serif type Unicode font designed especially for the Korean-language script, designed by HanYang System Co., Limited. It is an expanded version of Hanyang Gulrim.
In CJK computing, graphic characters are traditionally classed into fullwidth and halfwidth characters. Unlike monospaced fonts, a halfwidth character occupies half the width of a fullwidth character, hence the name.
In the Unicode standard, a plane is a contiguous 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 15.1, five of the planes have assigned code points (characters), and seven are named.
KPS 9566 is a North Korean standard specifying a character encoding for the Chosŏn'gŭl (Hangul) writing system used for the Korean language. The edition of 1997 specified an ISO 2022-compliant 94×94 two-byte coded character set. Subsequent editions have added additional encoded characters outside of the 94×94 plane, in a manner comparable to UHC or GBK.
KS X 1001, "Code for Information Interchange ", formerly called KS C 5601, is a South Korean coded character set standard to represent Hangul and Hanja characters on a computer.
CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages. It also contains one Chinese character.
Arabic Presentation Forms-B is a Unicode block encoding spacing forms of Arabic diacritics, and contextual letter forms. The special codepoint ZWNBSP is also here, which is only meant for a byte order mark. The block name in Unicode 1.0 was Basic Glyphs for Arabic Language; its characters were re-ordered in the process of merging with ISO 10646 in Unicode 1.0.1 and 1.1.
Hangul Jamo is a Unicode block containing positional forms of the Hangul consonant and vowel clusters. While the Hangul Syllables Unicode block contains precomposed syllables used in standard modern Korean, the Hangul Jamo block can be used to compose arbitrary syllables dynamically, including those not included in the Hangul Syllables block.
Hangul Jamo Extended-A is a Unicode block containing choseong forms of archaic Hangul consonant clusters. They can be used to dynamically compose syllables that are not available as precomposed Hangul syllables in Unicode; specifically, syllables that are not used in standard modern Korean.
Hangul Jamo Extended-B is a Unicode block containing positional forms of archaic Hangul vowel and consonant clusters. They can be used to dynamically compose syllables that are not available as precomposed Hangul syllables in Unicode; specifically, syllables that are not used in standard modern Korean.
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:
Enclosed CJK Letters and Months is a Unicode block containing circled and parenthesized Katakana, Hangul, and CJK ideographs. Also included in the block are miscellaneous glyphs that would more likely fit in CJK Compatibility or Enclosed Alphanumerics: a few unit abbreviations, circled numbers from 21 to 50, and circled multiples of 10 from 10 to 80 enclosed in black squares.
Halfwidth and Fullwidth Forms is the name of a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode. It is the second-to-last block of the Basic Multilingual Plane, followed only by the short Specials block at U+FFF0–FFFF. Its block name in Unicode 1.0 was Halfwidth and Fullwidth Variants.
GB 12052-89, entitled Korean character coded character set for information interchange, is a Korean-language character set standard established by China. It consists of a total of 5,979 characters, and has no relationship nor compatibility with South Korea's KS X 1001 and North Korea's KPS 9566.
KS X 1002 is a South Korean character set standard established in order to supplement KS X 1001. It consists of a total of 7,649 characters.
