How to Detect and Use UTF-8 Locale Equivalents on Windows?

Using UTF-8 Locale on Windows: Equivalents and Detection

If you're developing code that relies on the en_US.UTF-8 locale, understanding its equivalent on Windows and how to detect its presence is crucial.

Equivalent Locale on Windows

Previously, UTF-8 wasn't supported as the system locale due to potential compatibility issues. However, Microsoft gradually introduced support:

• Since Windows 10 build 17035, a beta option allows you to set the locale code page to UTF-8 (option: "Use Unicode UTF-8 for worldwide language support").
• In Windows 10 build 17134 (April 2018 Update), the Universal C Runtime supports using UTF-8 as the code page. To enable it, use setlocale(LC_ALL, ".utf8").
• Later versions of Windows 10 also support UTF-8 locale without requiring the beta flag. You can use the /execution-charset:utf-8 option while compiling with MSVC or set the ActiveCodePage property in appxmanifest.

Detection

To detect the presence of UTF-8 locale on Windows, you can use the getlocale() function. It returns a string representing the current locale setting. If the string contains "UTF-8," it indicates that UTF-8 locale is available.
