The second one is because the Texinfo manual intentionally doesn't use
UTF-8 as @documentencoding.  Whereas we do (also intentionally).

Others disagreed at the time, and so we decided quite some time ago to
use @documentencoding UTF-8 in all our manuals.  (It was not only
about the dashes; UTF-8 encoding causes quite a lot of other Unicode
characters to be output by makeinfo.)  I see no reason to reverse that
decision (and start all those arguments all over again).
