init: Change fallback locale to C.UTF-8

Browse source 
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`.
