I have been wondering about this again recently.

I dug through the NetBSD libc a little, looking for this, but I couldn't
find it.  Then I ran across this page today:

    http://www.gnu.org/software/libunistring/manual/libunistring.html#The-wchar_005ft-mess

This claims that, like Solaris, NetBSD uses a locale-dependent wchar_t
encoding.  If this is the case then disabling the wide character code is
probably the simplest approach that will do something sensible for you.

BTW, libunistring seems like a nice approach.  It is close to what I
wish wchar_t support actually looked like.  I am tempted to say we
should go that route, but of course that would mean adding another
dependency :-(
