[misc] Print console warning when setting non-existent locales (#4085)

* Dont silently fail setting new locale when it isnt available

Right now if the new locale being set is not available then it fails silently and just uses the existing global locale. A console warning would be useful to notify the user of such a failure.

* added missing semicolon

* Added console warn check.

* Fixed if condition.

* Add space
