Hi Gabriel,

Thanks a lot for the testing.

That is to be expected, the AMS symbol dump in PUA space was a quick
hack to make pre-unicode symbols available in an unicode world, pending
their normalisation.

That standardisation is long past (IIRC it occured by unicode 3.2
released in March 2002), so no newly created/updated font family is
going to place those symbols in PUA anymore.

Now adding the AMS symbols to new fonts has been slow, due to the large
amount of software hardcoding Symbol (and equivallent) and masking the
actual glyph userbase to font makers. It will accelerate with more apps
expecting plain unicode by default.

Thanks for the testing!

Regards,
