I don't think the calling of that function is pertinent; there is only
one call of it, and that is inside "(unless noninteractive ...)".
Presumably noninterative will be non-nil in batch mode.

Perhaps the problem is that that function (or some equivalent) isn't
being called, and Emacs is outputting non-displayable characters
regardless.
