Merge #17085: init: Change fallback locale to C.UTF-8

facb9a1315 init: Change fallback locale to C.UTF-8 (Wladimir J. van der Laan)

Pull request description:

  Much of our code assumes file system UTF-8 support, and this is a more realistic guess for modern systems anyway than the default character set (which would be ASCII only). So change the assumed fallback locale (if no locale is defined by the user or OS) to `C.UTF-8`.
