Current Windows versions and all back to Windows XP and prior Windows NT (3.x, 4.0) are shipped with system libraries that support string encoding of two types: 16-bit "Unicode" (UTF-16 since Windows 2000) and a (sometimes multibyte) encoding called the "code page" (or incorrectly referred to as ANSI code page). 16-bit functions have names suffixed with 'W' (from "wide") such as SetWindowTextW.
UTF-16 (16-bit Unicode Transformation Format) is a character encoding that supports all 1,112,064 valid code points of Unicode. [ 1 ] [ a ] The encoding is variable-length as code points are encoded with one or two 16-bit code units .
Microsoft adopted a Unicode encoding (first the now-obsolete UCS-2, which was then Unicode's only encoding), i.e. UTF-16 for all its operating systems from Windows NT onwards, but additionally supports UTF-8 (aka CP_UTF8) since Windows 10 version 1803. [5] UTF-16 uniquely encodes all Unicode characters in the Basic Multilingual Plane (BMP ...
Unicode, formally The Unicode Standard, [note 1] is a text 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 16.0 of the standard [A] defines 154 998 characters and 168 scripts [3] used in various ordinary, literary, academic, and ...
In addition, in Windows 7, this change enabled console windows to have the features of the Aero Glass theme. [8] On Windows NT and Windows CE, the screen buffer uses four bytes per character cell: two bytes for character code, two bytes for attributes. The character is then encoded in a 16-bit subset of Unicode . [9]
10 Control-X was commonly used to cancel a line of input typed in at the terminal. 11 Control-Z has commonly been used on minicomputers, Windows and MsDOS systems to indicate "end of file" either on a terminal or in a text file. Unix / Linux systems use Control-D to indicate end-of-file at a terminal.
In UTF-16, a BOM (U+FEFF) may be placed as the first bytes of a file or character stream to indicate the endianness (byte order) of all the 16-bit code units of the file or stream. If an attempt is made to read this stream with the wrong endianness, the bytes will be swapped, thus delivering the character U+FFFE , which is defined by Unicode as ...
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 high bit set. . Originally, such prohibitions allowed for links that used only seven data bits, but they remain in some standards and so some standard-conforming software must generate messages that comply with the restrict
