You mean the desired ones? (Presumably they are proper.) Yes.
It tries
"-*-symbol-*-*-*-*-%d-*-*-*-*-*-*-*"
What does
xlsfonts -fn "-*-symbol-*-*-*-*-*-*-*-*-*-*-*-*"
give on your system? I have
-adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific
-adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific
-adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific
-adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific
-adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific
-adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific
-adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific
-adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific

-adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific
-adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific
-urw-symbol-medium-r-normal--0-0-0-0-p-0-adobe-fontspecific
-urw-symbol-medium-r-normal--17-120-100-100-p-0-adobe-fontspecific
I presume we should have
"-*-symbol-*-*-*-*-%d-*-*-*-*-*-adobe-*"
but your listing will tell us the problem.
BTW, I think we should be giving the user some control over this, to get
adobe in preference to urw or iso10646 in preference to iso8859, or
whatever.
