I agree.  That's another bug report I suppose I should file with bug-texinfo,
I suppose.

By the way, this isn't something that began with my changes in March,
as Eli suggested earlier.  Emacs 24.3 shipped with some .info files in
UTF-8 and others in Latin-1, which means that in pretty much any locale,
standalone 'info' will misbehave on some Emacs info file or another.
The problem goes back at least to Emacs 23.1 in 2009 (that's as far back
as I cared to check).

This latter bug, too, is fixed by the latest proposed patch.
