actually older data than the stix table 

http://www.w3.org/2003/entities/2007xml/unicode.xml

which began life in Sebastian's jadetex distribution a lifetime ago.
Although I sync up with barbara from time to time...

But actually coverage in pmml2tex at the character level isn't that great
I was sort of hoping "someone" would sort that out automatically if I
dropped in (say) xetex and the stix fonts at the back end instead:-)
It does work in some real examples though (for example all the examples
in chapter4 of MathML3 are typeset with this).

there are some mechanically generated character level tests at the start
that exercise complete unicode blocks which you can't pass completely
without good font support (and there's a whole bunch or arabic and bidi
tests that I skipped altogether when I ran the tests last year) but the
remaining tests are fairly conservative in character usage,
concentrating mainly on interpretation of the mathml structure.
