Excludes undisplayed text (text marked with tags that set the
invisibility attribute) if @include_hidden_chars is %FALSE.
The returned string includes a 0xFFFC character whenever the
buffer contains embedded images, so byte and character indexes
into the returned string do correspond to byte and character
indexes into the buffer. Contrast with [method@Gtk.TextBuffer.get_text].
Note that 0xFFFC can occur in normal text as well, so it is not a
reliable indicator that a paintable or widget is in the buffer.
Returns the text in the range [@start,@end).
