Confirmed, thanks Hans.

Since mtools-4.0.0 a codepage is used that defaults to 850

I added "default_codepage=437" to /etc/mtools.conf and now I get:

Error converting to codepage 437 Invalid argument

So I assume that we need to ship iconv in the initrd.

I'll check tomorrow and report the results.
