.NET Core app configuration: Specify INI file encoding

Question

During startup of my app, I read configuration values from INI file:

configBuilder.AddIniFile("appsettings.ini");

However, encoding of appsettings.ini is different from UTF-8 (Windows-1250 in my case). Thus, there is a problem with all configuration values that contain diacritics.

Is there a way how to specify encoding of configuration file so that all configuration values are read properly?

(Changing encoding of appsettings.ini is not possible in my case.)

Answer 1

Here is what works for me

Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
var configText = File.ReadAllText("config2.ini", Encoding.GetEncoding("windows-1250"));
var ms = new MemoryStream();
ms.Write(Encoding.Default.GetBytes(configText));
ms.Position = 0;

IConfiguration config = new ConfigurationBuilder()
              .AddIniStream(ms)
              .Build();

ms.Dispose();
