[Development] RFC: Defaulting to or enforcing UTF-8 locales on Unix systems

AFAICS (from the public coin logs that dump the entire set of environment variables), nothing specifically sets any of the locale environment variables. In fact, no variables are set. You can check for yourself for example from the macOS log from one of the recent qtbase dev integrations:
The regular Apple Terminal appears to be the entity that sets LC_CTYPE before launching the shell - however the CI system is not using the Apple Terminal.
I see two options:
(1) Either assume that macOS is UTF-8.
(2) We add a script to the provisioning of macOS to always set the LC_CTYPE environment variable to have the value UTF-8 (or any other environment variable that you'd like).
Can you think of any other ways to resolve this?

Another possibility is that some script overrode LC_ALL to "C" so as to get
non-localised output. Please fix it to override to "C.UTF-8" or something that
works on a Mac.
