The meta element has two uses: either to emulate the use of an HTTP response header field, or to embed additional metadata within the HTML document. With HTML up to and including HTML 4.01 and XHTML, there were four valid attributes: content, http-equiv, name and scheme. Under HTML 5, charset has been added and scheme has been removed.

In some locales UTF-8N means UTF-8 without a byte-order mark (BOM), and in this case UTF-8 may imply there is a BOM. [75] [76] In Windows, UTF-8 is codepage 65001 [77] with the symbolic name CP_UTF8 in source code. In MySQL, UTF-8 is called utf8mb4, [78] while utf8 and utf8mb3 refer to the obsolete CESU-8 variant.

Content-Type: text/html; charset=utf-8: Permanent RFC 9110: Date: The date and time that the message was sent (in "HTTP-date" format as defined by RFC 9110) Date: Tue, 15 Nov 1994 08:12:31 GMT: Permanent RFC 9110: Delta-Base: Specifies the delta-encoding entity tag of the response.

The < meta charset = "UTF-8" > tag is technically redundant when coming directly from a web server configured to send the character encoding in an HTTP header, though it becomes useful when the HTML response is saved in an .html file, cache, or web archive. [10]
The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented typing systems are added.
