The Compatibility Encoding Scheme for UTF-16: 8-Bit ( CESU-8 ) is a variant of UTF-8 that is described in Unicode Technical Report #26. A Unicode code point from the Basic Multilingual Plane (BMP), i.e. a code point in the range U+0000 to U+FFFF, is encoded in the same way as in UTF-8. A Unicode supplementary character, i.e. a code point in the range U+10000 to U+10FFFF, is first represented as a surrogate pair, like in UTF-16 , and then each surrogate code point is encoded in UTF-8. Therefore, CESU-8 needs six bytes (3 bytes per surrogate) for each Unicode supplementary character while UTF-8 needs only four. Though not specified in the technical report, unpaired surrogates are also encoded as 3 bytes each, and CESU-8 is exactly the same as applying an older UCS-2 to UTF-8 converter to UTF-16 data.
80-707: The encoding of Unicode non-BMP characters works out to 11101101 1010yyyy 10xxxxxx 11101101 1011xxxx 10xxxxxx (yyyy represents the top five bits of the character minus one). The byte values 0xF0—0xF4 will not appear in CESU-8, as they start the 4-byte encodings used by UTF-8. CESU-8 is not an official part of the Unicode Standard, because Unicode Technical Reports are informative documents only. It should be used exclusively for internal processing and never for external data exchange. Supporting CESU-8 in HTML documents
160-510: A Document type declaration (informally, a "doctype"). In browsers, the doctype helps to define the rendering mode—particularly whether to use quirks mode . The original purpose of the doctype was to enable the parsing and validation of HTML documents by SGML tools based on the Document type definition (DTD). The DTD to which the DOCTYPE refers contains a machine-readable grammar specifying

The user would execute the encyclopedia's software program to see a menu that allowed them to start browsing the encyclopedia's articles, and most encyclopedias also supported a way to search the contents of the encyclopedia.

It had many writers, known as the Encyclopédistes . It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert . The Encyclopédie
400-734: A compendium of articles (either wholly or partially taken) from a specific encyclopedia. Four major elements define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production: Some works entitled "dictionaries" are similar to encyclopedias, especially those concerned with a particular field (such as the Dictionary of the Middle Ages , the Dictionary of American Naval Fighting Ships , and Black's Law Dictionary ). The Macquarie Dictionary , Australia's national dictionary, became an encyclopedic dictionary after its first edition in recognition of

Synonymous words and those related by the subject matter are to be found scattered around the dictionary, giving no obvious place for in-depth treatment.

In contrast with name-value pair attributes, there are some attributes that affect the element simply by their presence in the start tag of the element, like the ismap attribute for the img element.

In addition to defining and listing synonymous terms for

HTML elements are delineated by tags , written using angle brackets . Tags such as < img > and < input > directly introduce content into

As such, dictionary entries are not fully translatable into other languages, but encyclopedia articles can be. In practice, however, the distinction is not concrete, as there is no clear-cut difference between factual, "encyclopedic" information and linguistic information such as appear in dictionaries. Thus encyclopedias may contain material that
