Is there any command for command prompt through which I can know the default encoding of my system?
Just head to the 'Control Panel' → 'Regional and Language Options' → 'Advanced' tab.
Microsoft Docs has a solution to get the encoding for the operating system's current ANSI code page. You can use the following VB code:
'Declaration (FYI) 'Public Shared ReadOnly Property Default As Encoding 'Usage Dim value As System.Text.Encoding value = System.Text.Encoding.Default System.Console.WriteLine(value.WebName) ' (e.g.)
There are also syntaxes for C#, C++ and JScript. Have a look at Microsoft Docs for more info.
