I couldn't resist to implement this :-)

0. Create a working subdirectory and change into it.

1. Call the attached script `make-dvimapfiles'.  It creates 256 files
   `mapXX' to be used as map files for tfmtodit.  This is far from
   perfect since it always uses the `uXXXX' notation, but for CJK
   characters this is just fine.

2. From TeXLive, copy the CJK subfont TFM files for Unicode encoding,
   for example `gbsnuXX.tfm'.

3. Call the attached script `make-ditfiles' to create the groff font
   description files.  If a TFM subfont file is called `fooXX.tfm',
   the corresponding dit file is called `fooXX'.

   Install these files to your favourite `font/devdvi' directory.

4. Call the attached script `make-tmac' to generate a macro file.  It
   defines a single command to activate the CJK font; use this instead
   of issuing a `\f[...]' command.

5. The `mapXX' and TFM files can now be deleted since they are no
   longer used.

Doing the above for the gbsn font, I get the attached output.  The
calling sequence was

  groff -Tdvi -k -ww chinese-test-dvi > chinese-test-dvi.dvi
  dvipdfmx chinese-test-dvi

for ((i=0; i<256; i++)); do
  printf -v f "map%02x" $i

  rm -f $f
  for ((j=0; j<256; j++)); do
    printf "%d u%02X%02X\n" $j $i $j >> $f
  done
done

for i in *.tfm; do
  mapfile=`echo $i | sed -e 's/.*\(..\)\.tfm$/map\1/'`
  fontfile=`echo $i | sed -e 's/\.tfm$//'`
  echo $fontfile
  tfmtodit $i $mapfile $fontfile
done

.so gbsnu.tmac
.gbsnu
This is a test of Chinese in groff.
