That's what I see here too, but g_get_charset(), called in 
gp_cairo.c, is getting ANSI_X3.4-1968 (ascii).  The GLib reference 
says,

"A number of interfaces in GLib depend on the current locale in 
which an application is running. Therefore, most GLib-using 
applications should call setlocale (LC_ALL, "") to set up the 
current locale."

I tried sticking that exact invocation into gp_cairo.c, prior to 
the call to g_get_charset, and the latter then found UTF-8 OK.
