Where do Encoding. Default come from

Question

I change the value of "change system locale" in region to any value,but "System.Text.Encoding. Default" value in c# always UTF8,Why?

Answer 1

Hi @heyangben ,
According to the description in the document below

• On .NET Core, the Default property always returns the UTF8Encoding.
• In .NET Framework on the Windows desktop, the Default property always gets the system's active code page and creates a Encoding object that corresponds to it.

I think that it is permanently set to UTF8: https://source.dot.net/#System.Private.CoreLib/Encoding.cs,83.

In .NET Framework the behaviour is different: https://referencesource.microsoft.com/#mscorlib/system/text/encoding.cs,1425.
