The HTML version of the set union documentation
seems fine
http://python.active-venture.com/lib/set-objects.html

But the PDF version appears to have an mdash instead
of a vertical bar.

I deduce that this is a LaTeX translation that ignore's
Knuth's claim that we should not typeset | outside of
math mode (or even want to!), so I'm guessing
the same problem occurs elsewhere in the documentation.
The translation needs to be $|$ instead of just |.

How to report?

Thanks,
Alan Isaac
