This change is not equivalent to utf8=1. In the case of utf8=1, vfat
uses iocharset's conversion table and it can handle more than ascii.

So this patch is incompatible changes, and handles less chars than
utf8=1. So I think this is clean though, but this would be regression
for user of utf8=1.

Thanks.
