AW: Unable to get GROFF_ENCODING to seep through to sourced subfiles

[Walter Harms]

If that does not work try (assuming bash):
export GROFF_ENCODING=utf8
groff_pipeline

rationale:
doing
GROFF_ENCODING=utf8 groff_pipeline
is setting GROFF_ENCODING for the first element only, if anything later in the 
pipe needs that also it is lost. Using export means that subshell also have 
this value.

hope that helps

  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".
