 [No title]
Multi-octet characters, however, are not compatible with many current applications and protocols, and this has led to the development of a few so-called UCS transformation formats (UTF), each with different characteristics.
MIME registration This memo is meant to serve as the basis for registration of a MIME character set parameter (charset) [CHARSET-REG].
As long as a character set standard does not change incompatibly, version numbers serve no purpose, because one gains nothing by learning from the tag that newly assigned characters may be received that one doesn't know about.

 Universal character set : UCS   (Site not responding. Last check: )
The Universal Character Set is a character encoding shared with the Unicode Standard defined by the international standard ISO 10646.
There are several character encoding forms defined by ISO 10646 for the Universal Character Set.
The simplest is UCS-2, which uses a single code value between 0 and 65535 for each character, and allowing that value to be represented as exactly two bytes (one 16-bit word).

 97-10: Use of the universal code character set
Technique for Using Characters from the Universal Set in USMARC Records The second important charge of the Character Set Subcommittee was to develop a technique for using characters from the universal coded character set in USMARC records.
The character set used in records could be identified systematically by the presence or absence of binary zeros as the first eight bits in the record.
Although not all universal set characters have binary zero as the first eight bits, this 8-bit sequence of binary zeros would always occur at the beginning of a recorded encoded with the universal character set.

 Character Model for the World Wide Web 1.0: Fundamentals
A set of characters to be encoded is identified.
The character encoding form can be extremely simple (for instance, one which encodes the integers of the CCS into the natural representation of integers of the chosen datatype of the computing platform) or arbitrarily complex (a variable number of code units, where the value of each unit is a non-trivial function of the encoded integer).
A character encoding scheme is a mapping of the code units of a character encoding form (CEF) into well-defined sequences of bytes, taking into account the necessary specification of byte-order for multi-byte base datatypes and including in some cases switching schemes between the code units of multiple character encoding schemes (an example is ISO 2022).

 A tutorial on character code issues
Note: The set of nonnegative integers corresponding to characters need not consist of consecutive numbers; in fact, most character codes have "holes", such as code positions reserved for control functions or for eventual future use to be defined later.
A character may have a broader range of use than the most literal interpretation of its name might indicate; coded representation, name, and representative glyph need to be taken in context when establishing the semantics of a character.
characters with compatibility mappings: should they be used, or should the corresponding non-compatibility characters be used, perhaps with some markup and/or style sheet that corresponds to the difference between them.

 The recode reference manual: Universal
Standard ISO 10646 defines a universal character set, intended to encompass in the long run all languages written on this planet.
A multi-byte character always starts with a byte of 192 or more, and is always followed by a number of bytes between 128 to 191.
Character insertion or replacement might require moving the remainder of the string in either direction.

 Characters and Character Sets
Computer systems vary greatly in the sets of characters they make available for use in electronic documents; this variety enables users with widely different needs to find computer systems suitable to their purposes, but it also complicates the interchange of documents among systems; hence the need for a chapter on this topic in these Guidelines.
The same character may be represented by many different glyphs; less obviously, the same glyph, may in certain circumstances correspond with different abstract characters, or be used with different interpretations, as when, for example, the Greek capital letter omega is also used to represent the unit of electrical resistance (ohm).
Each of these mappings (from abstract character to number) is sometimes called a code point, and a character code is also often called a character set, though the same phrase is also often used as a synonym for both font and repertoire, as we have defined them here.

 Character Sets and Encoding - UCS/UNICODE
The characters that make up the content and markup of a Web page must be converted by the recipient software, such as a browser agent or an application, from the stored digital format back into the actual characters according to the character set and it's encoding.
This means that the traditional character sets such as ISO 8859-1 (used for most Western languages) can only define and encode a small number of characters yet it takes tens of thousands of characters to support all the languages of our world.
Character entity references (there is not a character entity reference for every character in the character set ISO 10646).

 Languages and Character Sets
We use the term coded character set (strictly) to mean the set of numeric values associated with a given character repertoire when it is represented in digital form.
A number of other phrases are sometimes used in place of `coded character set', including character code or character set, and the same phrase is also often used as a synonym for both font and repertoire, as we have defined them here.
Finally, we use the term encoded character to mean simply the numerical value associated with that abstract character in a given coded character set.

 Character encoding - Wikipedia, the free encyclopedia
Conventionally character set and character encoding were considered synonymous, as the same standard would specify both what characters were available and how they were to be encoded into a stream of code units (usually with a single character per code unit).
Multiple coded character sets may share the same repertoire; for example ISO-8859-1 and IBM code pages 037 and 500 all cover the same repertoire but map them to different codes.
However, there are also compound character encoding schemes, which use escape sequences to switch between several simple schemes (such as ISO 2022), and compressing schemes, which try to minimise the number of bytes used per code unit (such as SCSU, BOCU, and Punycode).

 Multilingual storage and retrieval - Patent 5778213
Each character set includes all of the characters used by the respective language (e.g., the letters of the English alphabet or the symbols of Kanji).
If the client must work with the database in a different character set, the entire database must be transferred to a server capable of supporting the different character set, or the client must convert the requested information into the different character set.
At step 32, the server determines whether the selected first set is already stored in the user-specified character set (i.e., the user requests the first set in its native character set or the first set has already been converted to the user-specified character set).

 Character Sets and Encodings
character set is a set of textual and graphic symbols, each of which is mapped to a set of nonnegative integers.
An application that uses a character set that cannot use the default encoding must explicitly set a different encoding.
If the client hasn't set character encoding and the request data is encoded with a different encoding from the default, the data won't be interpreted correctly.

 Universal Character Set - Wikipedia, the free encyclopedia
Characters (letters, numbers, symbols, ideograms, logograms, etc.) from the many languages, scripts, and traditions of the world are represented in the UCS with unique code points.
In 1990, therefore, two initiatives for a universal character set existed: Unicode, with 16 bits for every character (65,536 possible characters), and ISO 10646.
Meanwhile, in the passage of time, the situation changed in the Unicode standard itself: 65,536 characters came to appear insufficient, and the standard from version 2.0 and onwards supports encoding of 1,112,064 characters by means of the UTF-16 surrogate mechanism.

Unicode is a 16-bit character set designed to cover all the world's major living languages, in addition to scientific symbols and dead languages that are the subject of scholarly interest.
It eliminates the complexity of multibyte character sets that are currently used on UNIX and Windows to support Asian languages.
The first 256 values are the same as the ISO-Latin character set, which is also the basis for the ANSI Character set used in Windows 3.1 and Windows 95.

 HTML Document Representation
The document character set, however, does not suffice to allow user agents to correctly interpret HTML documents as they are typically exchanged -- encoded as a sequence of bytes in a file or during a network transmission.
A given character encoding may not be able to express all characters of the document character set.
If missing characters are presented using their numeric representation, use the hexadecimal (not decimal) form since this is the form used in character set standards.

 Universal Character Set
In their opinion, Unicode needs to display all characters set in JIS X 0213 (by any means), and needs to ensure that if a character is transferred from Unicode to JIS X 0213 or the reverse, it is possible to be restored just as it was before.
The other problem is description style of particular Kana characters used to represent language of Ainu, who is settled mainly in Hokkaido and have unique culture and language of their own.

 Sonic's Ultimate HTML Character Set pages
Thankfully, at the dawn of the new millennium, Unicode has become the standard character set for Microsoft Windows and the Mac OS (Apple and Xerox were early major proponents of the Unicode standard), as well as other essential platforms with which the author has insufficient familiarity to discuss here.
The beauty of all this: whether UTF-8 or an older, legacy character set is declared, the web page author may then generate and use any characters available, just as if using a word processor on that platform...
Since the author is an English-using American, the character set focus of these tables is almost exclusively Roman characters, Greek and characters from other languages commonly used in mathematics, and other symbols of interest to English-using Net users.

 unicode (Linux Reviews)
The UCS characters 0x0000 to 0x007f are identical to those of the classic US-ASCII character set and the characters in the range 0x0000 to 0x00ff are identical to those in ISO 8859-1 Latin-1.
For example, the German character Umlaut-A ("Latin capital letter A with diaeresis") can either be represented by the precomposed UCS code 0x00c4, or alternatively as the combination of a normal "Latin capital letter A" followed by a "combining diaeresis": 0x0041 0x0308.

 SP - SGML declaration
A character in a base character set is described either by giving its number in a universal character set, or by specifying a minimum literal.
Character numbers in the universal character set can be as big as 99999999.
This has the same meaning as a sequence of parameter literals one for each character number that is greater than or equal to the number of the character in the first parameter literal and less than or equal to the number of the character in the second parameter literal.

 Unicode: The Universal Character Set
To encode the over 13,000 characters of this character set it was necessary to develop escape sequences, similar to those used in the encoding of Chinese characters in library systems, to extend the meaning of the series of bytes.
This character set was called Big5, reportedly because it was a effort to standardize the character set over the five major computer companies operating in Taiwan at the time.
To reduce the total number of characters that had to be encoded, the group working on the universal character set (UCS) took advantage of the large number of characters that these languages shared due to their common origins.
