Whoops!  You're right.

This could be what's going on, but the "character not defined" warnings
suggest that groff _is_ successfully (though perhaps wrongly) setting the font
to something that lacks basic alphabetic characters (as ZD does), then running
into the string-comparison issue Deri noted (comment #1).  If groff were
seeking a phantom "ZDR" font, the font-setting should fail altogether, leaving
the font as TR, which I wouldn't expect to produce those particular warnings.
