Erich,
sorry for the late reply.

At least PS output works just fine; the normal steps given in the
`grops' manpage are valid, see below. groff's PDF output device
doesn't work; I suspect a bug (or it isn't implemented yet). However,
calling ghostscript's `ps2pdf' is OK -- since grops doesn't do font
subsetting, this step is almost mandatory since it reduces the file
size enormously.
I did the following to install `gbsn00lp.ttf', a Chinese font covering
the GB 2312 character set.
1. Call
fontforge gbsn00lp.ttf
to generate a `Type42' font (menu `File', then `Generate Fonts').
Output file: BousungEG-Light-GB.t42
2. Generate a `PS Type 1 binary' font; under `Options', select `Output AFM'.
Output file: BousungEG-Light-GB.afm
The also generated file `BousungEG-Light-GB.pfb' is not used and can be
deleted.
3. Copy the file `textmap' from groff's `font/devps/generate' directory to
the current directory.
4. Call
afmtodit BousungEG-Light-GB.afm textmap gbsn
to generate a groff font description file `gbsn'.
5. Move the files
BousungEG-Light-GB.t42
gbsn
into a groff font directory, for example
/usr/local/share/groff/site-font/font/devps
(see the troff(1) man page, environment variable `GROFF_FONT_PATH', for
the default search path on your machine).
6. Currently, groff reads a single `download' file only; a typical location
is for example
/usr/local/share/groff/current/font/devps/download
Append the following line to this file:
BousungEG-Light-GB BousungEG-Light-GB.t42
7. The UTF-8 encoded example file has been processed with
groff -k -ww chinese-test > chinese-test.ps
ps2pdf chinese-test.ps
Note that I had problems with ghostscript 9.00 and 9.04. However, a
self-compiled version 9.05 worked just fine.
Attached is a sample output.
For special handling of CJK punctuation characters, have a look into
groff's `ja.tmac' file; it should be easy to adapt this to Chinese.
Due to missing inter-character spacing support in groff, real CJK
typesetting isn't possible if you want justified text.
For grodvi, support is possible too, I think (using e.g. my gbsn
subfonts from TeXLive, called `gbsnuXX{.pfb,.afm}', with `XX' two
hexadecimal digits, and registering all those fonts with groff's
`.special' request), but I haven't tested it.

This is a test of Chinese in groff. Some phrases: \f[gbsn]\ 你 家 有 几 口 人 ? .br 你们 学校 有 多少 学生 ? .br 我 想 , 大概 有 三 万 个 . .br 老板 让 我 去 那里 工作 . \fP\ The end.
