  By using the '-V' option one can see the pipeline,
 that "groff" constructs, for example:

a) "groff -s -k -V file" shows:

preconv file | soelim | troff -Tps | grops

b) "GROFF_ENCODING=utf8 groff -s -V file" shows

preconv -eutf8 file | soelim | troff -Tps | grops

  To get the right order, a patch must by applied,
 for example, that in groff-bug #59442:

"groff -s -k -V file" shows then

soelim file | preconv | troff -Tps | grops

  This does not work, as "preconv" needs an explicit encoding,
 when it gets the data from the standard input.


"GROFF_ENCODING=utf8 groff -s -V file" shows then

soelim file | preconv -eutf8 | troff -Tps | grops


  or the "-K" option for "groff" can be used instead of
"GROFF_ENCODING".
