init: Change fallback locale to C.UTF-8
init: Change fallback locale to C.UTF-8

Much of our code assumes 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`.
