No, the point is that the release tarball contains UTF-8
info files, and that these are transformed to ASCII for installations
that prefer ASCII info files.  cp-ascii's UTF8-to-ASCII transformation
loses information; we can't ship ASCII info files in the tarball
and then transform those to the UTF-8 originals.

An ASCII default would have been better years ago, but these days
UTF-8 is the typical default encoding in GNUish distributions and
most users will be better off if UTF-8 is the default.
