2000-06-21 Havoc Pennington <hp@redhat.com> * gtk/gtktextiter.h: Use gunichar instead of gint when appropriate in the interfaces * gtk/gtktexttypes.c: Remove UTF functions, use glib stuff instead when possible. * gtk/gtktexttypes.h: Delete some unused constants * gtktextbtree.c, gtktextiter.c, gtktextsegment.c, gtktextview.c, testtextbuffer.c: use glib instead of custom unicode routines
