Request for mathematical symbols

This is a request for including mathematical symbols in Google Sans Code, say doublestruck, calligraphic, Fraktur, etc. ranges. I've made this request in view of the rapidly increasing applications of coding in mathematics and science, such as use of AI and formal theorem provers, which use some mathematical symbols. Greek support has already been requested: https://github.com/googlefonts/googlesans-code/issues/45.

Start by reviewing the requested mathematical symbol ranges and the related Greek-support issue at #45. The scope would need to be defined before work can begin; done would mean agreeing on the symbols to include in Google Sans Code and implementing the corresponding font glyphs.
