[[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 call]]s. 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. However Microsoft did not support [[UTF-8]] in its API until May 2019.

Before 2019, Microsoft emphasized UTF-16 (i.e. -W API), but has since recommended to use [[UTF-8]] (at least in some cases),<ref name="Microsoft-UTF-8" /> on Windows and [[Xbox]] (and in other of its products), even states "UTF-8 is the universal code page for internationalization [and] UTF-16 [... is] a unique burden that Windows places on code that targets multiple platforms. [..] Windows [is] moving forward to support UTF-8 to remove this unique burden [resulting] in fewer internationalization issues in apps and games".<ref name="Microsoft GDK" />

A large amount of Microsoft documentation uses the word "Unicode" to refer explicitly to the UTF-16 encoding. Anything else, including UTF-8, is not "Unicode" in Microsoft's outdated language (while UTF-8 and UTF-16 are both Unicode according to [[Unicode|the Unicode Standard]], or encodings/"transformation formats" thereof).
