Proper noun
UTF-16
(computing) Unicode Transformation Format-16; a Unicode encoding scheme which uses two-byte (16-bit) code units (singly for characters in plane 0, and in four-byte [32-bit] surrogate pairs for supplementary characters in planes 1 through 16).
Additional bits added by the UTF-16 encoding process are shown in black. Source: Internet
A high-surrogate code point (also known as a leading surrogate) followed by a low-surrogate code point (also known as a trailing surrogate) together form a surrogate pair used in UTF-16 to represent 1,048,576 code points outside BMP. Source: Internet
Code points in Planes 1 through 16 (supplementary planes) are accessed as surrogate pairs in UTF-16 and encoded in four bytes in UTF-8. Source: Internet
ED can start the encoding of a surrogate half that cannot be encoded in UTF-16 and are also invalid. Source: Internet
Early adopters tended to use UCS-2 (the fixed-width two-byte precursor to UTF-16) and later moved to UTF-16 (the variable-width current standard), as this was the least disruptive way to add support for non-BMP characters. Source: Internet
File names are limited to 255 UTF-16 code units. Source: Internet
