JAWS can be set up to deal with various Unicode characters however they want (e.g., by reading out the Unicode character name), so as long as the right characters are in the PDF, things should work.   Their problems with reading my PDF files came from *really* botched tagging (post-XeLaTeX) -- I was incorrectly assuming that the magical ASCII-translation problems I got on my Macs were a subset of the problems they were getting.

The Mac software can do some pretty awful things under Copy/Paste,
in particular with mathematical symbols.

Perhaps the worst is that it treats the symbols \aleph, \beth, \gimel
and \daleth  as if they were in the Unicode Hebrew block.
This may sound fine at first encounter, but it means that an RTL switch
is also inserted --- with no following reversion to LTR !
So everything subsequent on the same line comes out in reverse order.
