Hi Owen,

Thanks for the reply.  Right now, our input method does use
gtk_im_delete_surrounding() and gtk_im_get_surrounding(). 
Unfortunately, widgets in some key applications (e.g.: Evolution 2
composer, Firefox with Pango patches) don't implement it.

Yes, implementing them is the _right_ thing to do.  However, if we can
emulate backspace, an elegant workaround is on the way.  We already
tested an IM for QT 3.x along the same lines.

Also, we were expecting backspace to erase only the last unicode
character, but it erases a complete group of them!  I have tracked the
matter to GtkEditable and GtkOldEditable, but still couldn't figure
out a "fix" yet... :-(
