az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Describe the bug

Recently, my script run into this problem. My az script is run on Azure Pipelines. Here is my PowerShell script on Windows Server 2019 agent:

az deployment sub what-if `
    --name "main$(Get-Date -Format "yyyyMMddHHmmss")" `
    --location 'japaneast' `
    --template-file 'main.bicep' `
    --parameters  `
        "env=$(env.name)" `
        "projectName=$(projectName)" `
        "dbAdminAccount=$(sql.serveradmin.name)" `
        "dbAdminPwd=$(sql.serveradmin.password)"

Here is the error output:

ERROR: 'charmap' codec can't encode characters in position 4790-4801: character maps to <undefined>

For the following command, it works.

az deployment sub validate `
    --name "main$(Get-Date -Format "yyyyMMddHHmmss")" `
    --location 'japaneast' `
    --template-file 'main.bicep' `
    --parameters  `
        "env=$(env.name)" `
        "projectName=$(projectName)" `
        "dbAdminAccount=$(sql.serveradmin.name)" `
        "dbAdminPwd=$(sql.serveradmin.password)"

So the error only shows when running az deployment sub what-if command.

To Reproduce

Expected behavior

My script is running for more than 1 month. It works before. I found it's broken today.
