No strong opinion here - my test case earlier was "man csh" when
LC_CTYPE=en_US.UTF-8 where \*(ua renders an actual error.  Both ^ and
\ha render a caret here, so no objection from my side to such a
change.

At least on macOS (and using pstopdf from there), \ha seems like a 
small improvement over ^ in that Preview now actually finds
occurrences of ^ if you search for it.  It doesn't highlight the
carets but it now returns the pages with one on it (it doesn't find
the pages only containing ones that come from a ^ in the source).
