The Unicode Consortium or Unicode Inc. is a not-for-profit organization that coordinates the development of the Unicode standard. Its stated goal is to eventually enable computers to operate in all languages from around the world. The consortium develops and publishes a list of freely-available ...
he Unicode encoding scheme that serializes a UTF-32 code unit sequence as a byte sequence in little-endian format.
* In UTF-32LE, the UTF-32 code unit sequence <0000004D 00000430 00004E8C 00010302> is serialized as <4D 00 00 00 30 04 00 00 8C 4E 00 00 02 03 01 00>.
* In UTF-32LE, an initial byte sequence <FF FE 00 00> is interpreted as U+FEFF zero width no-break space.

Unicode (or UCS) Transformation Format, 7-bit encoding form, specified by RFC-2152.
Industry:Computer; Software
A multibyte encoding for text that represents each Unicode character with 1 to 4 bytes, and which is backward-compatible with ASCII. UTF-8 is the predominant form of Unicode in web pages. More technically: (1) The UTF-8 encoding form. (2) The UTF-8 encoding scheme. (3) “UCS Transformation Format 8,” defined in Annex D of ISO/IEC 10646:2003, technically equivalent to the definitions in the Unicode Standard.
Industry:Computer; Software
The Unicode encoding form that assigns each Unicode scalar value to an unsigned byte sequence of one to four bytes in length.
* In UTF-8, the code point sequence <004D, 0430, 4E8C, 10302> is represented as <4D D0 B0 E4 BA 8C F0 90 8C 82>, where <4D> corresponds to U+004D, <D0 B0> corresponds to U+0430, <E4 BA 8C> corresponds to U+4E8C, and <F0 90 8C 82> corresponds to U+10302.
* Any UTF-8 byte sequence that does not match the patterns listed in Table 3-7 is ill-formed.
* Before the Unicode Standard, Version 3.1, the problematic “non-shortest form” byte sequences in UTF-8 were those where BMP characters could be represented in more than one way. These sequences are ill-formed, because they are not allowed by Table 3-7.
* Because surrogate code points are not Unicode scalar values, any UTF-8 byte sequence that would otherwise map to code points D800..DFFF is ill-formed.
Industry:Computer; Software
The Unicode encoding scheme that serializes a UTF-8 code unit sequence in exactly the same order as the code unit sequence itself.
* In the UTF-8 encoding scheme, the UTF-8 code unit sequence <4D D0 B0 E4 BA 8C F0 90 8C 82> is serialized as <4D D0 B0 E4 BA 8C F0 90 8C 82>.
* Because the UTF-8 encoding form already deals in ordered byte sequences, the UTF-8 encoding scheme is trivial. The byte ordering is already obvious and completely defined by the UTF-8 code unit sequence itself. The UTF-8 encoding scheme is defined merely for completeness of the Unicode character encoding model.
* While there is obviously no need for a byte order signature when using UTF-8, there are occasions when processes convert UTF-16 or UTF-32 data containing a byte order mark into UTF-8. When represented in UTF-8, the byte order mark turns into the byte sequence <EF BB BF>. Its usage at the beginning of a UTF-8 data stream is neither required nor recommended by the Unicode Standard, but its presence does not affect conformance to the UTF-8 encoding scheme. Identification of the <EF BB BF> byte sequence at the beginning of a data stream can, however, be taken as a near-certain indication that the data stream is using the UTF-8 encoding scheme.
Industry:Computer; Software
Greek term for grave accent, used in polytonic Greek character names.
Industry:Computer; Software
A situation arising from two characters (or sequences of characters) being rendered indistinguishably.
Industry:Computer; Software
Characters ordered as they are presented for reading. (Contrast with logical order.)
Industry:Computer; Software
Marks placed above, below, or within consonants to indicate vowels or other aspects of pronunciation. A feature of Middle Eastern scripts.
Industry:Computer; Software
A character with the Hangul_Syllable_Type property value Vowel_Jamo.
* When not occurring in clusters, the term vowel is equivalent to syllable-peak character.
