Since 2014, W3C recommends to use only ampersand as query separator. [7] The form content is only encoded in the URL's query string when the form submission method is GET. The same encoding is used by default when the submission method is POST, but the result is submitted as the HTTP request body rather than being included in a modified URL. [8]
The quoted-printable encoding uses the equals sign as an escape character. URL and URI use %-escapes to quote characters with a special meaning, as for non-ASCII characters. The ampersand (&) character may be considered as an escape character in SGML and derived formats such as HTML and XML.
URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding , it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource ...
Numeric character references (e.g. [ or [) should not be used in external links because the ampersand character (&) has a special meaning in a URL. In excessive cases, an automatic percent encoder such as the one at W3 Schools (use the second JavaScript form under "URL Encoding Functions") is probably the simplest solution.
SGML derived the use from IBM Generalized Markup Language, which was one of many IBM-mainframe languages to use the ampersand to signal a text substitution, eventually going back to System/360 macro assembly language. In the plain TeX markup language, the ampersand is used to mark tabstops. The ampersand itself can be applied in TeX with \&.
The Media Fragments URI 1.0 (basic) syntax supports addressing a media resource along two dimensions (temporal and spatial) using the keywords t and xywh, and Media Fragments 1.0 URI (advanced) adds track and id. [17] Therefore, one can use the following media fragments URI in the src attribute of the audio or video HTML5 element:
This article lists the character entity references that are valid in HTML and XML documents. A character entity reference refers to the content of a named entity. An entity declaration is created in XML, SGML and HTML documents (before HTML5) by using the <!ENTITY name "value"> syntax in a document type definition (DTD).
