UTF-16UTF-16 (16-bitUnicode Transformation Format) is a character encoding that supports all 1,112,064 valid code points of Unicode. The encoding is variable-length as code points are encoded with one or two 16-bitcode units.
UTF-7UTF-7 (7-bitUnicode Transformation Format) is an obsolete variable-length character encoding for representing Unicode text using a stream of ASCII characters. It was originally intended to provide a means of encoding Unicode text for use in InternetE-mail messages that was more efficient than the combination of UTF-8 with quoted-printable.
UnicodeCharacter encoding standardUnicode (also known as The Unicode Standard and TUS) is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 18.0 defines 172,808 characters and 175 scripts used in various ordinary, literary, academic and technical contexts.
Word joinerThe word joiner (WJ) () is a Unicode format character which is used to indicate that line breaking should not occur at its position. It does not affect the formation of ligatures or cursive joining and is ignored for the purpose of text segmentation. It is encoded since Unicode version 3.2 (released in 2002) as U+2060WORD JOINER (⁠). The word joiner replaces the zero-width no-break space (ZWNBSP, U+FEFF), as a usage of the no-break space of zero width.Universal Character Set charactersComplete list of the characters available on most computers The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set. The Universal Coded Character Set, most commonly called the Universal Character Set (abbr.UTF-8UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. As of 2026, almost every webpage (99%) is transmitted as UTF-8. UTF-8 supports all 1,112,064 valid Unicode code points using a variable-width encoding of one to four one-byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes.

Internet Engineering Task ForceOpen internet standards organization The Internet Engineering Task Force (IETF) is a standards organization for the Internet responsible for the technical standards of the Internet protocol suite (TCP/IP). It has no formal membership roster or requirements and all its participants are volunteers. Their work is usually funded by employers or other sponsors.
ASCIICharacter encoding standardASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English-language–focused) printable and 33 control characters – a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup.Magic number (programming)In computer programming, a magic number or magic constant is a numeric literal in source code whose meaning is unclear to the reader. The term is also used outside of programming to refer to a number whose meaning is not obvious without additional knowledge — for example, some file formats are identified by an embedded magic number in the file (see list of file signatures).
Computer programInstructions a computer can executeSource code for a computer program written in the JavaScript language. It demonstrates the appendChild() method. The method adds a new child node to an existing parent node. It is commonly used to dynamically modify the structure of an HTML document.A computer program is a sequence or set of instructions in a programming language for a computer to execute.
MetadataData about other dataIn the 21st century, metadata typically refers to digital forms, but traditional card catalogs contain metadata, with cards holding information about books in a library (author, title, subject, etc.).Metadata (or metainformation) is data (or information) that defines and describes the characteristics of other data. It often helps to describe, explain, locate, or otherwise make data easier to retrieve, use, or manage.*As an Amazon Associate I earn from qualifying purchases.
