Changed this in git just now.
Note: you will likely need to set $LANG in init's environment
for setlocale(LC_ALL, "") to activate Unicode for your init.

    init: if libc-based Unicode support is on, run setlocale(LC_ALL,
"") at startup

    It is not clear why we were excluding init from this.
    The "getpid() != 1" clause was there from the beginning (2001)
    but not explained.
