I disagree.  It doesn't add much to accept weird characters.  UTF-8 is
full of chars that *look* identical but compare non-equal, its nuts to
send them to anything except a human reader if you can avoid it.

Because you *know* it's gonna break downstream stuff, and fixing bugs
is generally cheaper the closer you detect them to where they occur.
And that's the case here: the user doesn't know wtf is going on and
that the problem is really upstream of gnetlist.  It would be better
to set up gnetlist st by default it pukes on weird stuff that's going
to confuse downstream stuff.  If user's want kanji let them set an
option to get it.

So what?  In the meantime you haven't confused the heck out of users
for no real gain.

I disagree, for the reasons above.
