Remarks

This API is exclusively supported on .NET 6 and later versions, and only when the application utilizes the ICU library. However, in .NET, the ICU library is not always used by default, particularly in the following scenarios:

When the application runs on an operating system that does not have the ICU library, and the app does not utilize the app-local ICU feature.
When the globalization invariant mode or NLS mode is enabled on Windows.

If the application is running on a Windows OS version that lacks the ICU library, it has the option to opt-in and enable the usage of the ICU library through the app-local ICU feature.
