If you wish you can still navigate text buffer this way, though in the case you use UTF-8 character encoding, this can become increasingly unreliable. Should you have a need to do so, you can employ Gtk::TextBuffer#get_iter_at_offset(char_offset), which gets an iterator pointing to((*char_offset*))within the text buffer, and Gtk::TextIter#offset which returns the character offset of an iterator (note in both cases we mean character offset, not byte offset).
