I've been gone a while, so I don't know what the latest is.
But based on old knowledge...

1. Make sure that you Guile script files are UTF-8.  If they
are not, you'll need to explicitly put a "coding:"
declaration at the top of each file.

2. In the inner_main of your scm_with_guile call, 
try calling scm_setlocale.  Maybe something like this?
(This shouldn't make a difference, I think. 
But, if it does, it says something interesting.)

scm_setlocale( scm_variable_ref(scm_c_lookup("LC_ALL")),
scm_from_locale_string("") ); If that actually works, lemme know.
