David, I asked a question about this on the gtk-devel-list
https://mail.gnome.org/archives/gtk-devel-list/2017-January/msg00018.html last month. A lot I didn't know about this. For UTF-8 it is a bit complicated even for English. For GTK's case in-sensitive search they use a casefold function and a normalizing function. This way you can do a case in-sensitive search on strings with ligatures and accents. If you are just sticking with asci english chars then just converting and comparing case should work. There is a bit more to it though for UTF-8 and unicode chars. I worked on this a little bit so that I could understand it better. My last attempt was https://github.com/cecashon/OrderedSetVelociRaptor/blob/master/Misc/Csamples/search_textbuffer4.c The GTK developers are working on GTK4. GTK3.22 should be stable for 3. GTK2 or 3 is fine with me.
