It doesn't use a Posix locale.

This is defined in the file latin1.tmac.

This is not possible.  You could scan and parse the `LANG' environment
variable, then loading an appropriate language support file, but I
don't think this is a good idea since it won't work well for
multilingual documents.  Something like LaTeX's babel system would be
nice, but until now noone has written such a thing since groff is
still tightly bound to latin1.  I hope to start conversion to Unicode
