My problem is that I get this '[' as the default hyphen char, and I
dislike that. Even after editing troff.man and putting '.shc =' it it I
got the first hyphenated line with '[' at the line end (all others had
'=' there). See:

This manual page describes the GNU version of troff, which
       is  part  of  the groff document formatting system.  It is
       highly compatible with Unix troff.  Usually it  should  be
       invoked  using the groff command, which will also run pre[
       processors and postprocessors in the appropriate order and

It seems to me being an initialisation error somewhere in the code but I
am not able to find that place. 

There is in env.cc:  init_request("hc", hyphen_char);  and in 
input.cc:  init_charset_table(); and   init_hyphen_requests(); - they
should work properly. It is for sure an ascii dependency but I do not
understand the code enough deeply, I think.
