Ouch.

Yeah, how about we make x0108 the minimal acceptable version?
It was released in 2002, that seems plenty old to me.
If you agree, I will make the change.

I think there isn't much reason to do it, since we're planning to avoid
Solaris iconv completely. If somebody wants to make the effort, though,
it is fine by me.
