**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:

```ps1
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:

```txt
ERROR: 'charmap' codec can't encode characters in position 4790-4801: character maps to
```

For the following command, it works.

```ps1
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.
