Rather, older 8-bit encodings such as ASCII or ISO-8859-1 are still used, forgoing Unicode support entirely, or UTF-8 is used for Unicode. [citation needed] One rare counter-example is the "strings" file introduced in Mac OS X 10.3 Panther, which is used by applications to lookup internationalized versions of messages. By default, this file is ...
Microsoft was one of the first companies to implement Unicode in their products. Windows NT was the first operating system that used "wide characters" in system calls.Using the (now obsolete) UCS-2 encoding scheme at first, it was upgraded to the variable-width encoding UTF-16 starting with Windows 2000, allowing a representation of additional planes with surrogate pairs.
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 ...
Although Windows NT supported Unicode and attempted to encourage programs to use it, it only provided the 16-bit code units of UCS-2/UTF-16, despite the existing support for other multibyte character encodings. As many applications preferred to use 8-bit strings, Windows-1252 remained the most popular encoding on Windows even after it added ...
UTF-8 is also the recommendation from the WHATWG for HTML and DOM specifications, and stating "UTF-8 encoding is the most appropriate encoding for interchange of Unicode" [4] and the Internet Mail Consortium recommends that all e‑mail programs be able to display and create mail using UTF-8.
Simple character encoding schemes include UTF-8, UTF-16BE, UTF-32BE, UTF-16LE, and UTF-32LE; compound character encoding schemes, such as UTF-16, UTF-32 and ISO/IEC 2022, switch between several simple schemes by using a byte order mark or escape sequences; compressing schemes try to minimize the number of bytes used per code unit (such as SCSU ...
Unicode, in the form of UTF-8, has been the most common encoding for the World Wide Web since 2008. [75] It has near-universal adoption, and much of the non-UTF-8 content is found in other Unicode encodings, e.g. UTF-16. As of 2024, UTF-8 accounts for on average 98.3% of all web pages (and 983 of the top 1,000 highest-ranked web pages). [76]
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 typing systems are added.
