I have been looking around on the web and could not find a solution or a topic about it. My apologies if there is somewhere. When I use the write-error and redirect the output to a file it will result in weird symbols in the file. The other ones like write-warning or write-output work fine.

Steps to reproduce

Write-Output "Lalala" 1> C:\Temp\test.txt 
Write-Error "This is a test" 2>&1 >> C:\Temp\test.txt 
Write-Warning "Test Testt" 3>&1 >> C:\Temp\test.txt 
Write-Information "Information Information" 6>&1 >> C:\Temp\test.txt 

Expected behavior

Output in the file:

Lalala
C:\Users\MoonChild\Documents\huh.ps1 : This is a test
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,huh.ps1
Test Testt
Information Information

Actual behavior

Output in the file:

Lalala
�[91mWrite-Error: �[91mThis is a test�[0m
Test Testt
