In groff, \[ul], \[rn], and \[br] are not real characters.  Instead,
they are defined with drawing requests.  From ps.tmac (dvi.tmac and
the other driver macro files contain very similar code):

  .\" This is designed so that \(ul, \(rn and \(br form corners.
  .char \[ul] \v'.25m'\D'l .5m 0'\v'-.25m'
  .char \[br] \Z'\v'.25m'\D'l 0 -1m''
  .char \[rn] \v'-.75m'\D'l .5m 0'\v'.75m'
