### PowerShell: Running in ConstrainedLanguage mode
You're here because you've seen the following message:
```powershell
[WARNING] ConstrainedLanguage mode detected, unable to set console to UTF-8.
When using PowerShell in ConstrainedLanguage mode, please set the
console mode manually to UTF-8. See here for more information:
https://ohmyposh.dev/docs/faq#powershell-running-in-constrainedlanguage-mode
```
When running PowerShell in ConstrainedLanguage mode, we can't set the console to UTF-8. This will cause the prompt to be rendered incorrectly.
There's a few [options][utf-8] to set the console to UTF-8 from an OS perspective on Windows, other systems shouldn't be impacted.
To remove the message after manual configuration, you can add the following to your `$PROFILE` before importing oh-my-posh:
```powershell
$env:POSH_CONSTRAINED_LANGUAGE = 1
```
