I would like to let you know that I am working on this in my free time
and in that context I don't respond well to blame, "excuses", and so on.
If you would like for me to work on your bugs then I would appreciate it
if you would keep things constructive.  Thanks :)

Serious question tho: what sort of back-compatibility can there be with
a Guile that only supports latin-1 strings?  What property is it that
you are going for here?

My guess is that many people want exactly this behavior.  Only a guess
of course.

What about GUILE_INSTALL_LOCALE=require or something like that?  Does
that suit your needs?  If not, then:

How would this work?
