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'
