The character set is determined when mounting the filesystem, not when
creating it.  Recent kernels default to ascii here (see #833238), but I
am surprised that you have this problem in the installer already.

The kernel, run "reportbug $(uname -r)" to do so.  I think that the
fat-modules-*-di packages need to include nls_ascii.ko, which they
currently do not.
