Missing named properties about regexp-examples HOT 2 CLOSED

Notes to self, after a little more research --

Ruby already directly references the Unicode RFC. For example, for the \p{In Miscellaneous Mathematical Symbols-B} example above, we have: https://github.com/ruby/ruby/blob/3628eae2e754a7489feebc6f41371d42d2efcf3c/enc/unicode/11.0.0/name2ctype.h#L34478-L34482

Then, there is this tool in the ruby source code to parse and map property names according to the unicode docs: https://github.com/ruby/ruby/blob/7aaf5b2878210d4df03a84be8d514a553839a5ba/tool/enc-unicode.rb and a template for decomposing the properties: https://github.com/ruby/ruby/blob/4444025d16ae1a586eee6a0ac9bdd09e33833f3c/template/unicode_norm_gen.tmpl.

Lastly, note that ruby defines its unicode version here. And, due to this, we can access it at runtime via: RbConfig::CONFIG['UNICODE_VERSION'].

So in conclusion, I believe it should be possible to access ruby's unicode mappings which are built at compilation; probably with a native C extension. Failing that, the above code should provide enough hints to reproduce the mapping generation as part of the gem installation process if necessary.

Either way, this solution would be far superior to the current db/ folder implementation.
