- I have searched the existing issues
Describe the bug
\r Characters are stripped from aarch64 output.
Create a new API application for .NET Core, we are using 8. Put the following code in.
var builder = WebApplication.CreateSlimBuilder(args);
var app = builder.Build();
var todosApi = app.MapGroup("/");
todosApi.MapGet("/", () => "Text\r\nMore text multinewline\r\n1\r\n2\r\n3");
app.Run();
1 .Build for x86 and for aarch64 from the linux CLI using a single file deployment.
2. Deploy to a x86 maching and an aarch64 machine.
3. Run the API request from the command line by calling the appropriate URL when deployed.
on x86 you get Text\r\nMore text multinewline\r\n1\r\n2\r\n3 as the output
on aarch64 you get Text\nMore text multinewline\n1\n2\n3 as the output.
All \r characters are stripped from the output.
Expected Behavior
x86 and aarch64 return the same unmodified string.
Text\r\nMore text multinewline\r\n1\r\n2\r\n3 is the output.
