A better temporary solution is probably to add a single flag like -D1
and -D0 to activate interpretation of double-byte characters
independently of the output device.  Additionally, an environment
variable like GROFF_DBCS might help to permanently activate it for
Japanese users.

This `poor' design is due to the age of troff.  BTW, TeX has similar
flaws, and the designer of LaTeX 2e had a lot of work to fix it.

I'm going to fix this for groff 2.0 by implementing Unicode,
separating input and output encoding, but it won't be a quick
development process...
