Sure.  There are a couple of approaches.

One is to use groff's special character escape sequences as you showed
above.

Like this:

$ cat ATTIC/2112a.groff
They've taken care of everything!
.rj
\[em] \[u2112]\[u2112]\[u2118]
.pl \n[nl]u
$ nroff ATTIC/2112a.groff

Another approach is to put UTF-8 in your source document, and then use
the '-k' option to nroff or groff to run preconv(1).

$ cat ATTIC/2112b.groff
They've taken care of everything!
.rj
— ℒℒ℘
.pl \n[nl]u
$ nroff -k ATTIC/2112b.groff

In either case you get the same output.

--end snip---

Does this work for you?  Is there anything else we can help with?
