Issue Description
The live logger is somehow corrupting the output of dotnet test, turning ~ characters into _ characters, but not all of them 🙃.
Steps to Reproduce
Repro
dotnet new xunit (I haven't tried other frameworks to know whether this is xunit specific).- Add the following test:
[Fact]
public void Test1()
{
var tildeString = new string('~', 5);
Console.WriteLine($"String length: {tildeString.Length}");
Console.WriteLine($"Each char code: {string.Join(", ", tildeString.Select(c => (int)c))}");
Console.WriteLine($"Hex dump: {BitConverter.ToString(System.Text.Encoding.UTF8.GetBytes(tildeString))}");
Console.WriteLine($"String: {tildeString}");
Assert.True(false, tildeString);
}Live logger disabled
When run as MSBUILDLIVELOGGER=false dotnet test (or the equivalent powershell), the following output happens:
➜ MSBUILDLIVELOGGER=false dotnet test

Versions & Configurations
I've reproduced this on various versions between 9.0.106 and 10p7, on bash and zsh (Ubuntu 24.04) and powershell (Windows 11). I was unable to reproduce this on any version of .NET 8 that I tried. I also tested a few other characters, and did not see any other corruption.
