Ansi colors not working in devops agent, does not always respect "NO_COLOR", only works with "__SuppressAnsiEscapeSequences" #19961
Description
Prerequisites
- Write a descriptive title.
- Make sure you are able to repro it on the latest released version
- Search the existing issues.
- Refer to the FAQ.
- Refer to Differences between Windows PowerShell 5.1 and PowerShell.
Steps to reproduce
Running powershell scripts in Azure DevOps agent, by turning on the "Use PowerShell Core" option. Even though Azure DevOps is unable to display ansi colors, pwsh still prints them into the logs. If environment variable NO_COLOR is assigned, it reduces the amount of ansi colors printed.
This is probably the exact same issue as mentioned here closed few weeks ago: #19188
Expected behavior
Expected to see clear output without ANSI colors messing up the whole thing generally in Azure DevOps because it is unable to render them. If that's not possible to do by default, at least when NO_COLOR is specified.Actual behavior
Dir by default:

Looks ok so far, but then if an error happens:
2023-07-13T08:03:54.6876706Z �[31;1mCheck the spelling of the name, or if a path was included, verify that the path is correct and try again.�[0m

When environment variable __SuppressAnsiEscapeSequences defined, then this is fixed too:
2023-07-13T08:08:11.1173976Z Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
