I believe that this is relevant:
http://www.gtkmm.org/docs/glibmm-2.4/docs/reference/html/classGlib_1_1ustring.html#_details
(see "Glib::ustring and stream input/output")

I think you need to know what encoding your string has, and convert it
when appropriate. You should also catch exceptions for when this fails.
