Your problem about using UTF16 is related to the fact you are using windows os and not linux or unix or macos x. All the others use utf-8 EXCEPT WINDOWS. There are functions to convert to and from whatever strings you need. Look up internationalization stuff, texttools. UTF16 is akin to what windows calls wchar(wide char) by the way. That should nudge you in the right direction for that. Also be careful what functions you use in window to debug print your strings. i.e. wprintf != printf. use wprintf with wchar string use printf with ascii strings etc... > > I am still not going to pursue using GTK+ in this project of mine, having > moved on to a better supported and more mature GUI toolkit, but I thought that > any feedback, even negative feedback, would be a good thing, since there might > be other people out there like me that aren't getting answers to simple > problems like this one. > > Now they know. > _______________________________________________ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list > _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
