Hmm, what setup exactly would be fixed by this?

Utf8 mode is always enabled by default in the kernel. so we should be
fine by only disabling if we want to support legacy setups.

What setup do we want to support here that disables this first from
userspace or the kernel command line, and we later want to enable it
again? If vt.default_utf8=0 is given on the command line, we should
probably not overwrite it here.
