Attempts to undefine ordinary characters (U+0021..U+007E) silently fail.


$ nroff
.nf
abc
.rchar a
abc
.pl \n(nlu
abc
abc


They should gripe at the user instead.  This would also help users who might
assume that they only need to specify a special character _identifier_ as an
argument to `rchar` or `rfschar`.  Instead you need the full special character
escape sequence syntax.
