Are you using Glib::ustring anywhere in the process of getting the data from the SQL database to the view?
Glib::ustring implicitly (and in my opinion still at least not well enough documented/hinted at) converts from UTF-8 to the current locale with operators << and >>. If you are using a stringstream anywhere in the process, or are using operator<< or operator>> in any other way, this could then be the cause of the problem. Otherwise, and in the above described case too actually it would help very much if you could post (if possible, all of) the relevant code online. Regards, M.
