$ echo '\[vs]' | groff -z -Tutf8
$ echo '\[vs]' | groff -z -Tlatin1
troff:<standard input>:1: warning: special character 'ah' not defined
The warning is expected, as _ลก_ does not exist in Latin-1. But the character
reported is weird.
Groff 1.22.4 correctly reported "can't find special character 'vs'." The
diagnostic is wrong in 1.23 and git HEAD.
