OK, so I tried latin1, too.  (replacing scm_from_utf3_string with
scm_from_latin1_string).  That also does not work.  It replaced the
0xA9 character with '?'.  What it all boils down to is that
I am looking for string handling functions that will handle the
NUL terminated list of bytes and keep its nose out of the contents
of the string.  Period.  Full stop.

So what is left?

I do not want to write my own ag_scm_from_zbytes_string(n) functions.
Such a function would need to remain portable to any and all internal
wiggling by Guile.  And it would need to work with the string scanning
functions, or I'd have to rewrite all of those too.  Or are strings
tagged with the content type, thus making it possible to call the
correct string scanning functions?  Of course, that would mean adding
the "zbytes" functions anyway....

You're welcome.  I did figure it was something like that.
