How can I change the BitLocker pre-boot authentication localization / internationalization display language?
I can change the OS language easily but what about the pre-boot environment?

I would suggest using this with caution and maybe doing more research as I have not personally tried this, but from the recovery environment I believe that you can do something like this:

bcdedit /set {current} locale en-US

In the meantime, I think that you will need to first provide the recovery key before you can get to the recovery environment.

The "locale" option looks undocumented:

Tried the command and says "The operation completed successfully" or something like that, however the language is not changed even after a reboot.
