Many keys will generate key press events but return an empty string from `xkb_state_key_get_utf8`, like modifier keys, arrow keys, function keys, etc. This checks if the string retrieved from such a key press is empty before emitting an associated text event for it, to avoid notifying a potentially large number of listeners about an empty string.
