UTF-16 (16-bit Unicode Transformation Format) is a character encoding method capable of encoding all 1,112,064 valid code points of Unicode. [ a ] The encoding is variable-length as code points are encoded with one or two 16-bit code units .
A CCSID (coded character set identifier) is a 16-bit number that represents a particular encoding of a specific code page.For example, Unicode is a code page that has several character encoding schemes (referred to as "transformation formats")—including UTF-8, UTF-16 and UTF-32—but which may or may not actually be accompanied by a CCSID number to indicate that this encoding is being used.
The Standard Compression Scheme for Unicode (SCSU) [1] is a Unicode Technical Standard for reducing the number of bytes needed to represent Unicode text, especially if that text uses mostly characters from one or a small number of per-language character blocks. It does so by dynamically mapping values in the range 128–255 to offsets within ...
This article includes a list of general references, but it lacks sufficient corresponding inline citations. Please help to improve this article by introducing more precise citations. (July 2019) (Learn how and when to remove this message) This article compares Unicode encodings in two types of environments: 8-bit clean environments, and environments that forbid the use of byte values with the ...
Converts Unicode character codes, always given in hexadecimal, to their UTF-8 or UTF-16 representation in upper-case hex or decimal. Can also reverse this for UTF-8.
Control codes are handled distinctly from ordinary Unicode characters, for example, by not being assigned character names (although they are assigned normative formal aliases). [1] In a broader sense, other non-printing format characters, such as those used in bidirectional text, are also referred to as control characters by software; [2] these ...
The format is the same as for any entity reference: &name; where name is the case-sensitive name of the entity. The semicolon is required. Because numbers are harder for humans to remember than names, character entity references are most often written by humans, while numeric character references are most often produced by computer programs.

A Unicode character is assigned a unique Name (na). [1] The name is composed of uppercase letters A–Z, digits 0–9, hyphen-minus and space.Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed.
