Maybe what follows doesn't apply to your version of nroff.  I run DWB 2.0
on an ATT 3b2, and was informed of the following undocumented feature:

You can enter 8-bit characters in the "charset" table by preceding it with a 
"%".

For example (for an IBM character set printer):

*a 1 %\340
*b 1 %\341
bu 1 %\371


This way you can also use the foreign language characters by creating
the appropriate string (Any 2-character name):

a' 1 %\240
