This refers to Isabelle/b138cdd22cfb.

That is a spin-off from the Z Notation support, because that requires
additional blackboard-bold symbols.

I've always found the approximation from AMS rather crude, and actually Joris
van der Hoeven (TeXmacs) agrees with that, see
https://www.texmacs.org/joris/fontart/fontart.html

The ultimate source for LaTeX symbols is
https://tug.ctan.org/info/symbols/comprehensive/symbols-a4.pdf --- table 316
on page 123 was relevant for the hint on txmia/txfonts.
