setup for English/Japanese

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

I would welcome advice on the sequence of steps needed to get vim to
work on files that are mixed English and Japanese, utf-8.  I run stock
NetBSD 7.0 on amd64, and habitually (it's a long-standing habit) use
csh.  There are several vim versions in pkgsrc; there
is a tutorial document on netbsd.org that seems to recommend using
urxvt, and makes mentions a few shells but not csh.

I've spent half a day trying to get things to work without success (on
MS Windows I just call up gvim and it works out of the box, but that's
very inconvenient in other ways).  Is there a step-by-step guide
anywhere?
