Hey, this stuff really does work!

Consider the attached PDF and open it in Preview, or TeXShop 2.

Select some of the math symbols, then Copy/Paste into TextEdit
or other recent editor -- a TeXShop editor window will do.

Neat huh.

Also, searching works in Preview  (not TeXshop !);
e.g.  use Apple-F to open the 'Search' panel,
then search for occurrences of \alpha .
You should find some --- however, they do *not*
highlight in the PDF, when you select one of these.

None of these nice features work in AR though (version 7.0.1).
So it's not so clear just who supports the /ToUnicode  tables,
and in what way.

I'd appreciate reports of other software that handles these
to some extent, or other.
