What does the symbol mean with 2 barbs to the bar...?

It's supposed to look something like the letter Z -- hence, a Zener diode.



I have seen the two barbs being each at an angle to the horizontal bar,
representing a zener, and the two barbs perpendicular to the bar,
representing a Schottky diode. Schottky diodes also seen as the more
elaborate curl at each end of the bar, as shown in the Wiki reference.
