I applied the patch by hand (diff didn't like it and it was trivial),
and indeed that does solve my original problem.  Could/should this be
included in the official reportlab codebase?

Using u"\u2206" for the increment (aka Delta) works, as does u"\u2126"
for Ohms (aka Omega).  Using u"\u00b5" for the micro sign (aka mu)
works fine, but interestingly the four built in fonts I was using all
seem to include their own versions of this character.  Note that
python will shorten this to just u'\xb5' which is equivalent (drops
the leading double zero).

Thanks for your help!
