UTF-16 (16-bit Unicode Transformation Format) is a character encoding that supports all 1,112,064 encodable code points of Unicode. [1] The encoding is variable-length as code points are encoded with one or two 16-bit code units.
Code chart ∣ Web page Note : [ 1 ] [ 2 ] [ 3 ] Halfwidth and Fullwidth Forms is a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode.
Characters in this range require 16 bits to encode in both UTF-8 and UTF-16, and 32 bits in UTF-32. For U+0800 to U+FFFF, the remaining characters in the Basic Multilingual Plane and capable of representing the rest of the characters of most of the world's living languages, UTF-8 needs 24 bits to encode a character while UTF-16 needs 16 bits ...

UTF-16 – Extends UCS-2 to cover the whole of Unicode with sequences of one or two 16-bit elements; GB 18030 – A full-Unicode variable-length code designed for compatibility with older Chinese multibyte encodings; Huffman coding – A technique for expressing more common characters using shorter bit strings than are used for less common ...
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 writing systems are added.
UTF-16 was devised to break free of the 65,536-character limit of the original Unicode (1.x) without breaking compatibility with the 16-bit encoding. In UTF-16, singletons have the range 0000–D7FF (55,296 code points) and E000–FFFF (8192 code points, 63,488 in total), lead units the range D800–DBFF (1024 code points) and trail units the ...
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.
